This is based on spv.paramMemory.frag.out which exercises the
writeonly storage image case.
This appears to need desktop GLSL.
The generated SPIR-V fails validation because the image_write function
takes a parameter which is pointer to an OpTypeImage with Unknown format.
But the parameters passed in are pointer to OpTypeImage with formats Rgba32f
and Rgba16f. The validator rejects this, saying the parameter types must
match.
This change strips a few features similar to GLSLANG_WEB but doesn't
remove every detail like the latter. It also hardcodes profile/version
to core/450.
In particular, TBuiltIns::initialize is specialized to remove most of
what is not supported or won't be supported by ANGLE. The result of
this function is parsed with TParseContext::parseShaderStrings which is
a performance bottleneck.
This change shaves about 300KB off of ANGLE's binary size and reduces
the cost of SetupBuiltinSymbolTable to nearly a sixth.

This problem needs to be fixed, but in parallel, we need to see master
and any other changes to it passing all tests.
The removed test is ray-tracing centric, and may indicate non-determinism
in recent code added for that functionality.

`glslang_pch()` did manual mangling of the compiler flags to enable pre-compiled headers.
I couldn't get this approach to work with the `MachineIndependent` subdirectory, but fortunately CMake has added first-class support for precompiled headers in 3.16, which does work with subdirectories.
Moved `glslang_pch()` to the other global function declarations.
`glslang_pch()` is a no-op when using CMake earlier than `3.16`.
CMake's PCH implementation does not need the `pch.cpp` files, so just remove them.
This adds or changes binding/location decorations in 100s of shaders.
It also allows more output (spv.register.autoassign.rangetest.frag)
due to allowing ioMap() to fail.
Fix#2298.
The AST has two precisions, an operation precision and a result precision.
Actual use of GLSL with mediump samplers wants the result precision, so
pick that up instead of the operation precision.
* 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.
If a uniform has an initializer it will now be given as the optional
initializer operand to the OpVariable instruction.

* rework how shader interface block naming rules are handled
* Fixes 2136
According to the spec, shader interfaces (uniform blocks, buffer
blocks, input blocks, output blocks) all should be matched up via
their block names across all compilation units, not instance names.
Also, all block names can be re-used between all 4 interface types
without conflict. This change makes it so all of these blocks are
matched and remapped using block name and not by instance name.
Additional the rule that matched uniform and buffer blocks must
either be anonymous or named (but not nessearily the same name) is
now imposed.
* add warning if instance names differ between matched shader interfaces
* Add test cases from #2137 which is now fixed as well.
* replace some tab characters with spaces
* buffer blocks and uniform blocks now share the same block namespace
* Fixes#2005
Allow multiple units in a stage to have push_constants as long
as the blocks match.
Requires #2006 to be fixed to be functional.
* tweaks to #2005 fix after some testing
* add unit tests for push constants across multiple compilation units
For #2005
* update reference output for tests that fail validation
* fix uninitialized result.validationResult
