Fixed compile warning in reflection.cpp for ENABLE_HLSL = 0 build. [-Wunused-parameter]

Update SPIRV-Tools known-good: validate OpImageRead result type

See #2486

Pick up https://github.com/KhronosGroup/SPIRV-Tools/pull/4072
which validates the result type of OpImageRead.

This also requires test expectation updates.

See #2486 tracks the needed upate to Glslang code generation.

Issue #2483

According to GLSL spec the prototype is:
        uint rayQueryGetIntersectionInstanceShaderBindingTableRecordOffsetEXT(rayQueryEXT q, bool committed);

but that was incorrectly getting translated to SPIRV as an `int`, and this was
causing SPIR-V validation errors when used.

Added explicit testing for the return types of all the builtin functions in GL_EXT_ray_query

Update README to avoid googletest breakage

Additional fix for #2480

* update spirv-headers and fix handling of gl_HitTEXT

Update spirv-headers known_good to f027d53ded7e230e008d37c8b47ede7cd308e19d
and update SPIRV/spirv.hpp to copy from that version as well.

In GLSL gl_HitTNV/gl_HitTEXT is defined as an alias of gl_RayTmaxNV/gl_RayTmaxEXT
SPV_NV_ray_tracing has a dedicated HitTNV which gl_HitTNV maps to.
For SPV_KHR_ray_tracing, gl_HitTEXT gets mapped to a RayTmaxKHR decoraged variable
to simplify the SPIRV consumer.
This change fixes the mapping for the GL_EXT_ray_tracing extension, and updates
the test results to match.

* update MissNV shader test to not use ObjectRay builtins

They shouldn't existing in the miss stage because there is no object intersected

* Add ray query capability if acceleration structure used

Fixes #2430

in non-ray tracing stages and the extension is enabled

* Add ray query capability if ray query declared

* Fix printing of TypeRayQueryKHR

It's no longer spelled with "Provisional"

* Fix traceRay/executeCallable to have id instead of constant.

Update to final (non-provisional) SPIR-V capabilities
(includes review feedback)
- Change visibilty of findLinkerObjects.

Fixes a crash in ANGLE.

Closes: #2452

set, but the incoming unit does not

Use of gl_Layer and gl_ViewportIndex in tessellation and vertex
shaders should not trigger the addition of the Geometry capability.

Fixes #2461

Added tests for use of gl_Layer and gl_ViewportIndex in a tessellation
evaluation shader.

Several tests for NVIDIA features for tessellation, vertex, or mesh
shaders now lose the Geometry or MultiViewport capabilities.
This is ok because the functionality is already covered by
the ShaderViewportIndexLayerNV capability.

The spv.meshShaderPerViewBuiltins.mesh test now fails validation
because the validator does not know that PrimitiveId (and possibly
other) builtins are enabled by the MeshShadingNV capability.
I filed https://github.com/KhronosGroup/SPIRV-Headers/issues/179 to
fix the grammar upstream.

This implements a new nonunifom analysis suggested by @jbolz. This change
generates nonUniform decorations that were previously missing and avoids
generation of incorrect decorations. Most notably, it now generates
decorations for nonuniform functions and out params. It avoids generating
decorations for lvalues which themselves are not nonuniform.

Fixes #2443

ATT.

* Code refine and adding missing features

1. Add new level for built in symbols.
2. Fix issues for structure members' qualifiers.
3. Global qualifier fix.
4. IO Mapper refine. Add support for checking with mangle names.

* Additional missing features

* Invariant member. (Only check non-interface).

* Split block nesting level and struct nesting level. To fix issues of checking 'invariant' qualifier.

Current grammar would check block/struct member without its parent class's information.
So we split nesting level, and 'invariant' would only be checked within a struct.

* Format anonymous block names. Refine codes for symbols from all kinds of resouces.

* Fix writeonly check.

* Use LValueBase to find operator.

* Fix random null ptr issue.

* invariant check, stage in io mapping, reference parameter should be used and remove wrong codes introduced with ordering vector.

* Remained: to be fixed with double check link.vk.multiblocksValid

* Fix version error.

invariant

* Revert loc modification.

Getting error about undefined symbol (include_dir) at line 320.
Was trying to append to a non-existant variable.

Bug #2445

* Add new SpirvToolsDisassemble API interface + Improve Doc on existing API interface (#2408)

* Add more flexible SpirvToolsDisassemble interface to allow specifying spv_target_env for disassembly output.
Improve documentation on existing SpirvToolsDisassemble interface.

* Update pre-processor check - following existing ENABLE_OPT checks.

* Fix not-found header paths for glslangValidator and glslangtests.

* Add spirv_tools/include path where there is an ENABLE_OPT=1 in the BUILD.gn configuration.

* When targeting SPIR-V 1.5, using gl_ViewportIndex will emit OpCapability ShaderViewportIndex and using gl_Layer will emit OpCapability CapabilityShaderLayer. OpCapability ShaderViewportIndexLayerEXT will only get emitted if the target < SPIR-V 1.5

* When using one of the viewport/layer arrays extensions, fallback to OpCapability ShaderViewportIndexLayerEXT, even when targeting SPIR-V 1.5

* Revert "When using one of the viewport/layer arrays extensions, fallback to OpCapability ShaderViewportIndexLayerEXT, even when targeting SPIR-V 1.5"

This reverts commit dccca82f4076ea6e2bc01dd6d1e5d290c59fab20.

* Using gl_Layer and gl_ViewportIndex outside of the geometry shader stage still requires one of the viewport extensions even when targeting SPIR-V 1.5
(Fixes a problem introduced by 670536b663f396815645b2f907f0ee92117b44f0)

* Do not use PropagateLineInfoPass and RedundantLineInfoElimPass

Since spirv-opt will remove PropagateLineInfoPass and
RedundantLineInfoElimPass, glslang should not use it. spirv-opt will
propagate the line instructions and eliminate the redundant lines by
default in IR loading/emission.

* Update known_good.json for spirv-tool

NonUniform SPIR-V fixes.

HLSL: Add support for printf().

Translate printf() to what GL_EXT_debug_printf has done. HLSL could
define non-constant string variable and we don't have such features
in SPIR-V, so just support constant string variable.

Fix GN build and presubmits

Add missing `.cfg` files for GN presubmit.
Add missing `recursedeps` in the `DEPS` file.
Call `./update_glslang_sources.py` before attempting to build.
Add more GN spew to the `.gitignore` file.

Kokoro: Add configurations for GN presubmit

Add GL_EXT_fragment_shading_rate

Issue: #2421

Add basic GN configurations

TIntermediate was constructed without initializing any of the `resources` fields,
and `TProgram::linkStage()` was not calling `TIntermediate::setLimits()`
after constructing new `TIntermediate`s for non-first stages.

Fields of `resources` were then read in `TIntermediate::finalCheck()`
triggering undefined behavior.

This CL makes three changes:
(1) `TIntermediate::setLimits()` is now called for non-first stages by
    copying the `firstIntermediate`'s limits. This ensures that the
    `resources` fields is initialized, fixing the bug.
(2) `TIntermediate::resources` is now wrapped in a `MustBeAssigned<>`
    helper struct, asserting in non-release builds that this field is
    always initialized before reading.
(3) `TIntermediate::resources` is now zero-initialized, so that if
    the `TIntermediate::resources` field is not set in a release build
    (and so the `assert()` will be disabled) behavior is still
    deterministic.
