Unify opaque type validation in GLSL parsing
Refactor separate sampler and image validations into unified opaque
type handling. This paves way for adding atomic counter, another
new opaque type.

Inherit privately from angle::NonCopyable.
Make all inheritance from angle::NonCopyable private so the compiler
complains about this (admittedly unlikely) code:
class Foo: angle::NonCopyable {
virtual ~Foo() { ... }
};
angle::NonCopyable *p = new Foo;
delete p;
In the above code ~Foo() is not called, only ~NonCopyable(), because the
latter is not virtual. Making it virtual would add overhead to all derived
classes which don't already have a virtual method.
Also tighten access in NonCopyable, because we can.

GLSL parser: Fix empty declaration qualifier checks
The shader validation now does the same checks for qualifier
combinations regardless of if a declaration is empty, as is specified.
Some of these checks used to be in singleDeclarationErrorCheck, and
have now been moved to a new function declarationQualifierErrorCheck.
The other parts of singleDeclarationErrorCheck are under a renamed
nonEmptyDeclarationErrorCheck.
The patch also contains another related cleanup: Unnecessary symbol
nodes won't be created for empty declarations any more.

Fix assert when attempting to create a void array node
TIntermTyped::CreateZero can be reached with a void array type in an
error case. Handle this gracefully instead of asserting.
Also remove an assert that wasn't really checking anything in
CreateZero. type.isScalar() || type.isVector() || type.isMatrix() can
only be false in case of a struct, and struct type was being checked
in the condition on the line above.

Never add declarations without children to the AST
When block nodes were being created for loop bodies that didn't have
braces in the parsed source, the code didn't check if the loop body
was a declaration node without children. Always use appendStatement()
for adding statements to a block, so that declaration nodes without
children don't end up in the AST.
Similarly make sure that loop init nodes aren't declarations without
children.

Prefer identifying functions by using symbol ids
The shader translator code is now structured in a way that ensures
that all function definition, function prototype and function call
nodes store the integer symbol id for the function. This is guaranteed
regardless of whether the function node is added while parsing or as a
result of an AST transformation. TIntermAggregate nodes, which include
function calls and constructors can now only be created by calling one
of the TIntermAggregate::Create*() functions to ensure they have all
the necessary properties.
This makes it possible to keep track of functions using integer ids
instead of their mangled name strings when generating the call graph
and when using TLValueTrackingTraverser.
This commit includes a few other small cleanups to the CallDAG class
as well.

Implement location layout qualifier for uniforms
This is a complete implementation of the uniform location layout
qualifier. Uniform location set in the shader is plumbed to shader
linking, which does several link-time checks for conflicts and
recursively applies the location to struct members.
Validate that location is consistent as specified in the table in
section 9.2.1 of the ESSL 3.10.4 spec. The location set in the shader
overrides the one set via the CHROMIUM_bind_uniform_location API.
Location conflicts must be checked even if the uniforms are not
statically used. Because of this unused uniforms are now recorded
during uniform linking. After linking checks are done, unused uniforms
are pruned from the program state.
Location is validated against the maximum number of uniform locations
at compile time as specified in section 4.4.3 of the ESSL 3.10.4 spec.
All dEQP uniform location tests don't yet pass due to unrelated bugs.

Unify and simplify shader variable collection
Instead of setting variable information in both CollectVariables and
the GetVariableTraverser helper class it uses, keep all of this
functionality in CollectVariables. A single helper function handles
setting variable information that doesn't depend on variable type, and
the rest is done in "record" functions that are implemented for each
variable type.
This removes templates from the code, making it leaner and easier to
understand, and will help with implementing future features like
adding binding and location layout qualifiers for uniforms.

This fixes setting of gotPrecisionFromChildren in a few cases.

Fold user-definedness of function nodes into TOperator
Whether a function call is user-defined is not orthogonal to TOperator
associated with the call node - other ops than function calls can't be
user-defined. Because of this it makes sense to store the user-
definedness by having different TOperator enums for different types of
calls.
This patch also tags internal helper functions that have a raw
definition outside the AST with a separate TOperator enum. This way
they can be handled with logic that is easy to understand. Before this,
function calls like this left the user-defined bit unset, despite not
really being built-ins either. The EmulatePrecision traverser uses
this. This is also something that could be used to clean up built-in
emulation in the future.

Vulkan: Implement new GLSL translator back-end.
The Vulkan GLSL translator back-end will handle validating and
translating our WebGL/ESSL shaders into Vulkan-specific GLSL.
glslang (the Vulkan one) accepts both GLSL and GLSL ES shaders
as inputs, and both the desktop and ESSL back-ends give
incompleteness warnings when used. For now, use the desktop GL
450 as a target for Vulkan GLSL.
The Vulkan-specific changes are currently only to add locations
to every vertex input and fragment output.

Add ESSL 3.10 integer math built-ins
This adds built-ins found in ESSL 3.10 section 8.8 Integer functions.
This includes constant folding support for functions that may be
constant folded, and support for both GLSL and HLSL output. In HLSL
several of the functions need to be emulated.
The precision qualification for the return value of some of these
functions is determined by special rules, that are now part of type
promotion for TIntermUnary nodes and determining the type of
TIntermAggregate nodes.

Also, now that ops that are not function calls don't use the

than to use a whitelist.

Make AST path always include the current node being traversed
AST traversers tend to sometimes call traverse() functions manually
during PreVisit. Change TIntermTraverser so that even if this happens,
all the nodes are automatically added to the traversal path, instead
of having to add them manually in each individual AST traverser.
This also makes calling getParentNode() return the correct node during
InVisit.
This does cause the same node being added to the traversal path twice
in some cases, where nodes are repeatedly traversed, like in
OutputHLSL, but this should not have adverse side effects. The more
common case is that the traverse() function is called on the children
of the node being currently traversed.
This fixes a bug in OVR_multiview validation, which did not previously
call incrementDepth and decrementDepth when it should have.

Remove extraInfo parameter from compiler diagnostic functions
This makes error messages more consistent. It was not clear what was
supposed to go to the extraInfo parameter, and previously it was
mostly being misused, resulting in poorly formatted error messages.
Sometimes the order of parameters to the diagnostic functions like
error() and warning() was wrong altogether. The diagnostics API is
simpler when there's only the "reason" and "token" parameters that
have clear meaning and that are separated by consistent punctuation
in the output.
Fixes error messages like
"redifinition interface block member"
to be grammatically reasonable like the rest of the error messages. For
other error messages, punctuation is added to make them clearer. Example:
"invalid layout qualifier location requires an argument"
is changed to
"invalid layout qualifier: location requires an argument".
Extra spaces are also removed from the beginning of error messages.

Split TIntermInvariantDeclaration from TIntermAggregate
This change is pure refactoring and doesn't fix bugs related to
invariant declarations. Invariant declarations are supposed to accept
a list of identifiers, but this refactoring keeps the current behavior
of only accepting a single identifier in an invariant declaration.
When the bug will be fixed, the new TIntermInvariantDeclaration class
that now has only a single child node can be changed so that it may
have multiple children.
TIntermAggregate is still used for function calls, function
prototypes and function parameter lists.

Work around atan(y, x) bug on NVIDIA
atan(y, x) is not always returning expected results on NVIDIA OpenGL
drivers between versions 367 and 375. Work around this by emulating
atan(y, x) using the regular atan(x) function. A fix to the driver is
expected in a future release.
It is most convenient to implement the vector atan(y, x) functions by
using the scalar atan(y, x) function. Support for simple dependencies
between emulated functions is added to BuiltInFunctionEmulator. In the
current implementation one function is allowed to have at most one
other function as its dependency.

In TranslatorHLSL a number of AST simplifications are done, that must
happen in a precise order for things to be correct:
- First for-loops must be split
- Then multideclarations must be split
- Finally comma operators must be split
This adds tests for interaction between this passes to make sure they
are done in the right order.

gl_WorkGroupSize should be written into the AST as a constant node
instead of a symbol node. In correct shaders, local size is guaranteed
to have been declared before any references to gl_WorkGroupSize -
otherwise the shader translator was already generating an error.
This ensures that work group size can be used to size arrays as
specified and also works around a crash issue on NVIDIA Linux OpenGL
driver.

Previously infinity and NaN resulting from constant folding would be

Handle constant folding arithmetic involving infinity
Constant folding arithmetic operations that involve infinity are now
handled correctly in the cases where the result is infinity or zero.
The implementation mostly relies on C++ to implement IEEE float
arithmetic correctly so that unnecessary overhead is avoided.
Constant folding arithmetic operations that result in overflow now
issue a warning but result in infinity. This is not mandated by the
spec but is a reasonable choice since it is the behavior of the
default IEEE rounding mode.
Constant folding arithmetic operations that result in NaN in IEEE will
generate a warning but the NaN is kept. This is also not mandated by
the spec, but is among the allowed behaviors.
There's no special handling for ESSL 1.00. ESSL 1.00 doesn't really
have the concept of NaN, but since it is not feasible to control
generating NaNs at shader run time either way, it should not be a big
issue if constant folding may generate them as well.

Fix GLSL float parsing corner cases
This fixes parsing floats that are out-of-range, and floats that have
more digits than the standard library float parsing functions can
handle. In these cases, we now fall back to a custom implementation of
float parsing. The custom parsing path can correctly process floats
with up to hundreds of millions of digits in their mantissa part.
Rounding behavior of the custom float parser may not be entirely
consistent with the standard parser, but the error should be at most
a few ULP. This can be considered acceptable since floating point
operations are not expected to be exact in GLSL in general. Settling
for lower accuracy also enables the parser to run in constant memory,
instead of having to store all the significant digits of the decimal
mantissa being parsed.

translator: Put ShaderLang APIs in "sh" namespace.
Working with glslang in Vulkan means we are static linking libANGLE
with functions that have the same name as our translator APIs. We
can fix this by scoping our APIs. We don't need to scope the types
of the file, since they don't conflict.
This will require a follow-up patch to remove the unscoped APIs
once we switch over Chromium.
We also scope TCompiler and some related classes to avoid multiply
defined link errors with glslang.
