When location aliasing, the aliases sharing the location must have the same underlying numerical type and bit width (floating-point or integer, 32-bit versus 64-bit, etc.) and the same auxiliary storage and interpolation qualification.
This adds checks for the "patch" and "sample" qualifiers, and also relaxes the checks when the signedness of integer types differs.
* location aliasing
when location aliasing, the aliases sharing the location must have the same underlying numerical type
(floating-point or integer) and the same auxiliary storage and interpolation qualification.
The following case, glslang need report error.
layout(vertices = 1) out;
layout (location = 1, component = 0) in double gohan[];
layout (location = 1, component = 2) in float goten[];
in vec4 vs_tcs[];
out vec4 tcs_tes[];
void main()
{
}
* Need consider the following case: location aliasing with different interpolation qualifier.

Oes spec says:
For the both the input array gl_SampleMaskIn[] and the output array gl_SampleMask[], bit B of mask M
(gl_SampleMaskIn[M] or gl_SampleMask[M]) corresponds to sample 32*M+B. These arrays have
ceil(gl_MaxSamples/32) elements, where gl_MaxSamples is the maximum number of color samples
supported by the implementation.
But glslang report error "array must have size before use length".
layout(location = 0) out mediump vec4 fragColor;
void main (void)
{
for (int i = 0; i < gl_SampleMask.length(); ++i)
gl_SampleMask[i] = int(0xAAAAAAAA);
fragColor = vec4(0.0, 1.0, 0.0, 1.0);
}
* Add two test items, one is for gl_MaxSapmles = 32 and the other one is for gl_MaxSapmles = 64.
Move the parameter verifictation to a centralized place where all the builtins
are verified for correctness.
Add verification for the new builtins with version and extension check
These builtins are supported on GLSL since version 130 and GLES since
version 300.
Add missing callgraph clean for bindless status flag.
Add test cases. Add support to check special extensions not be available for Vulkan when using GLSL.
The glsl spec says:A shader will fail to compile if the value passed to the mem argument of an atomic memory function does not
correspond to a buffer or shared variable.
* Implement GL_EXT_terminate_invocation.
* terminateInvocation: declare the SPV extension
* Update test results for spirv-tools and bison version bumps

* Fix xfb_stride limit issue
Unsized array can't apply to transform trace. layout qualifier "offset" require GL_ARB_enhanced_layouts enable or glsl core version > 440.
* Add negative test for xfb limit
* update case result
* Fix compile information issue
Fix compile information issue and test comment issue.
* remove es profile condition, use profileRequires to limit.
* Fix xfb_stride limit issue
Unsized array can't apply to transform trace. layout qualifier "offset" require GL_ARB_enhanced_layouts enable or glsl core version > 440.
Add negative test for xfb limit
* Move es profile check out of version number check
* Adjust error information and related cases
remove the new version check, refine original version check.
* Revert condition for vulkan, and remove redundant test code.
Focus was on the front end (not SPIR-V), minus the grammar.
Reduces #ifdef count by around 320 and makes the web build 270K smaller,
which is about 90% the target size.
The grammar and scanner will be another step, as will the SPIR-V backend.
This makes heavy use of methods #ifdef'd to return false as a global way
of turning off code, relying on C++ DCE to do the rest.
with subgroup touch tests (error and non-error cases)
Currently the subgroup built-ins are NOT giving the correct output.
This is fixed in the next commit.
with subgroup touch testing (error and non-error cases)
Add missing symbolTable.relateToOperator("subgroupMemoryBarrierShared") call for
Mesh/Task shaders so they don't assert in ParseHelper.cpp
(and GL_NV_shader_subgroup_partitioned) based on GL/ES version
instead of predicating it on vulkan SPV generation
Also add AST testing.
The glsl.450.subgroup* files are largely the same as the spv.subgroup*
The glsl.es320.subgroup* files are the same as the 450 versions, but modified to be ES compatible.
