Translator: Allow tree validation in children of TCompiler
This is to be able to perform validation inside TranslatorVulkan, even
if it's through ASSERTs.
Additionally, every transformation is changed such that they do their
validation themselves. TIntermTraverser::updateTree() performs the
validation, which indirectly validates many of three tree
transformations. Some of the more ancient transformations that don't
use this function directly call TCompiler::validateAST.

Standardize copyright notices to project style
For all "ANGLE Project" copyrights, standardize to the format specified
by the style guide. Changes:
- "Copyright (c)" and "Copyright(c)" changed to just "Copyright".
- Removed the second half of date ranges ("Y1Y1-Y2Y2"->"Y1Y1").
- Fixed a small number of files that had no copyright date using the
initial commit year from the version control history.
- Fixed one instance of copyright being "The ANGLE Project" rather than
"The ANGLE Project Authors"
These changes are applied both to the copyright of source file, and
where applicable to copyright statements that are generated by
templates.

Vulkan: Compute shader support
A DispatchHelper class is created as the equivalent of FramebufferHelper
as a command graph resource. There's currently a single dispatcher and
all dispatch calls are recorded on that. Context dirty bits are set up
in such a way that graphics and compute workloads are independently
handled, so that issuing a dispatch call wouldn't cause a framebuffer's
render pass to rebind resources.

Track parameter qualifiers of functions in call nodes
We now add a reference to TFunction to all TIntermAggregate nodes
where it is possible, including built-in ops. We also make sure
that internal TFunctions added in traversers have correct parameter
qualifiers.
This makes TLValueTrackingTraverser much simpler. Instead of storing
traversed functions or looking up builtin functions from the symbol
table, determining which function parameters are out parameters can
now be done simply by looking it up from the function symbol
associated with the aggregate node.
Symbol instances are no longer deleted when a symbol table level goes
out of scope, and TFunction destructor no longer clears the
parameters. They're all either statically allocated or pool allocated,
so this does not result in leaks.

Prune no-op statements with a single traverser
We put pruning literal statements and pruning empty declarations in
the same traverser, as some of the required logic is the same. This
pruning of no-ops is always done as one of the first processing steps
after parsing, so further processing of the AST is simpler.
Since we now prune pure literals before removing no-op cases from the
end of switch statements, we also don't need any sort of special
handling for switch statements in pruning pure literals.

2. Non-empty fall-through cases in switch/case.

Only support GL_OVR_multiview extension variant
The WebGL spec proposal was changed so that only GL_OVR_multiview
extension name is supported, instead of having two variants
OVR_multiview and OVR_multiview2. We're only supporting the WebGL
version of the shader extension, so we drop compiler support for
GL_OVR_multiview2. Shader restrictions were also removed from the
WebGL spec, so no special validation for how ViewID_OVR gets used is
needed.
Tests that were testing for the shader restrictions are either removed
or changed from negative tests to positive tests.

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.

Remove invariant declaration in vertex shader for translation from ESSL 3.00 to GLSL <= 4.1
This is a follow-up patch of
https://chromium-review.googlesource.com/408569. This CL removes
invariant declaration in ESSL 3.00 vertex shader, such like:
"
out vec4 foo;
invariant foo;
"
This CL also adds the workarounds in libANGLE.

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.

Reland "Remove invariant qualifier for input in fragment shader"
This relands https://chromium-review.googlesource.com/#/c/400005/.
ESSL and GLSL are not consistent on invariant matching in vertex shader
and fragment shader. See the following rules:
ESSL 1.00 - input and output must match
ESSL 3.00 - only output, inputs cannot be declared as invariant.
GLSL 1.10.59 - does not exist
GLSL 1.20.8 - input and output must match
GLSL 1.30.10 - input and output must match
GLSL 1.40.8 - input and output must match
GLSL 1.50.11 - input and output must match
GLSL 3.30.6 - input and output must match
GLSL 4.00.9 - input and output must match
GLSL 4.10.6 - input and output must match
GLSL 4.20.11 - input can omit invariant
GLSL 4.30.8 - input can omit invariant
GLSL 4.40.9 - input can omit invariant
GLSL 4.50.5 - input can omit invariant
Since GLSL 4.20, invariant qualifier description were changed to:
"
Only variables output from a shader (including those that are then input
to a subsequent shader) can be candidates for invariance. This includes
user-defined output variables and the built-in output variables. As only
outputs need be declared with invariant, an output from one shader stage
will still match an input of a subsequent stage without the input being
declared as invariant.
"
It's not very clear if input in fragment can be declared as invariant.
Mesa driver disallows use of input declared as invariant in fragment
shader, while other drivers may allow it. This CL removes invariant
declaration for input in fragment shader except AMD driver in Linux.
AMD's driver obviously contradicts the spec by forcing invariance to
match between vertex and fragment shaders.

Flatten "#pragma STDGL invariant(all)" into varying variables.
This is implemented as a compiler option which is enabled by default
when outputting to desktop GLSL version 130 and greater, which does
not support this #pragma in fragment shaders. As a workaround, and for
better compatibility on desktop OpenGL drivers, this pragma is also
flattened into the outputs of vertex shaders, and the inputs of ESSL
1.00 fragment shaders.

Support is added for compute shader compilation. There is a small
extension to the parser so that 'local_size_x = ', 'local_size_y = '

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.

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.
