Simplify queueReplacement AST transform helper
queueReplacement is always called to replace the node that's currently

Mark some internal functions as not having side effects
Precision emulation rounding function calls and vector/matrix dynamic
indexing function calls now get a flag that indicates that running the
function body does not have side effects. This avoids triggering
asserts in OutputHLSL when these internal function calls end up on the
right hand side of a non-unfolded logical operator.

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.

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.

Split TIntermBlock from TIntermAggregate

the EOpSequence op. It represents the root node of the tree which is

that can be denoted by curly braces. These include function and loop
bodies, and if-else branches.
This change enables a bunch of more compile-time type checking, and
makes the AST code easier to understand and less error-prone.
The PostProcess step that used to be done to ensure that the root node
is TIntermAggregate is removed in favor of making sure that the root
node is a TIntermBlock in the glslang.y parsing code.
Intermediate output formatting is improved to print the EOpNull error
in a clearer way.

Support precision emulation on HLSL
Re-submit with missing virtual destructor and angle::NonCopyable
added.
Add precision emulation support to HLSL 4.1 output. This makes it
possible for developers to test their shaders for precision issues
easily on Chrome on Windows without having to use the GL backend. The
patch has been verified with Chrome on Windows to reproduce some
precision bugs in real-world WebGL content, including old versions of
the babylon.js library.
The EmulatePrecision AST transformation still relies on writing out
raw shader code for the rounding functions, with raw HLSL code added
alongside pre-existing GLSL and ESSL code. In some ways it would be
nicer to do the EmulatePrecision step as a pure AST transformation,
but on the other hand the raw code is much more readable and easier
to optimize.
To better support multiple output languages in EmulatePrecision, add a
RoundingHelperWriter class that has different subclasses for writing
the rounding functions in different languages.
The unit tests are expanded to cover the HLSL output of precision
emulation. The parts of the tests that require the HLSL output are
only active on Windows where ANGLE_ENABLE_HLSL define is added to the
unit tests. Putting the HLSL tests in an entirely separate file is a
worse alternative, since it would require either a lot of code
duplication or add a lot of boilerplate to the individual tests.

Support non-square matrices in precision emulation
In case the shader version is greater than ESSL 1.00, the precision
emulation needs to output rounding functions for non-square matrix
types.
Writing emulated compound assignment functions for non-square matrices
already had most of the code in place before this change.
New compound assignment operators like >>= don't need floating point
precision emulation in ESSL 3.00, since all of them only operate on
integers.

Reuse code for determining built-in type name string
Add TType::getBuiltInTypeNameString() that returns an unique char
pointer for each built-in type. They can be easily stored in an
std::set as required by EmulatePrecision, and the function can also
be used in TOutputGLSLBase.

Set correct type on nodes created in precision emulation
The correct type needs to be set so that HLSL output will be able to
disambiguate user-defined function calls correctly based on argument
types. HLSL output support will be added to precision emulation in a
future patch, which will also have tests that verify this patch.
The lack of correct type on the nodes is not known to cause any bugs
in GLSL output.

Remove EOpInternalFunctionCall
It's cleaner to mark internal functions by using the TName class,
similarly to TIntermSymbol.

Detect when built-in modf requires an l-value in AST traversal
This fixes an omission that out parameter tracking had inherited from
EmulatePrecision. Accurate tracking of when values are written is
required for converting dynamic indexing of vectors and matrices to
function calls.
A new test covering this is added to angle_unittests.

Refactor l-value tracking to a separate traverser parent class
This makes TIntermTraverser implementation easier to understand and
removes the overhead of maintaining the user-defined GLSL function table
from the traversers that don't need it.
Some logic is duplicated between TIntermTraverser and its new subclass
TLValueTrackingTraverser, but duplication is hard to eliminate completely
since there are some differences scattered throughout the code.

Track where l-values are required in AST traversal
This functionality is refactored out of EmulatePrecision to be a common
feature of TIntermTraverser. This is done since tracking where l-values
are required will be useful for other traversers. For example, it will
be needed for converting dynamic indexing of matrices and vectors to
function calls. This change adds some overhead to all tree traversers,
but the overhead is expected to be small for typical shaders which don't
contain too many user-defined functions.

Add an SH_GLSL_CORE_OUTPUT profile.
So we could generate shaders for Apple using core GL profile.
By switching to core profile, we still pass most WebGL conformance tests 1.0.2 on Linux, but not all, so apparently more work is needed.
However, I think it's OK to check this CL in because this output profile will be only used behind a chromium switch.

Avoid precision emulation overhead on unused values
Avoid rounding intermediate values when the intermediate value is not
consumed. For example, this avoids rounding the return value of
assignment, so "b = a;" becomes "b = frm(a);" instead of "frm(b =
frm(a))".

Add mediump and lowp precision emulation support for GLSL output
This implements the rounding as specified in WEBGL_debug_shader_precision
extension proposal for desktop GLSL and ESSL output. The bulk of the new
functionality is added in the form of a new EmulatePrecision AST
traverser, which inserts calls to the rounding routines angle_frm and
angle_frl in the appropriate places, and writes the rounding routines
themselves to the shader.
Compound assignments which are subject to emulation are transformed from
"x op= y" to "angle_compound_op_frm(x, y)", a call to a function which
does the appropriate rounding and places the result of the operation to
x.
The angle_ prefixed names should not clash with user-defined names if
name hashing is on. If name hashing is not on, the precision emulation
can only be used if the angle_ prefix is reserved for use by ANGLE.
To support the rounding routines in output, a new operator type is added
for internal helper function calls, which are not subject to name
hashing.
In ESSL output, all variables are forced to highp when precision
emulation is on to ensure consistency with how precision emulation
performs on desktop.
Comprehensive tests for the added code generation are included.
