GLSL: Support constant folding for mod

GLSL: Fix semantic error for GL_KHR_memory_scope_semantics

When 2DMS or 2DMSArray is used, IMAGE_PARAMS will take an additional
paramter to represent sample number. The semantics check should get the
correct semantics values, taking this case into account.

glslang.js: Make the SPIR-V target version configurable (1.0 ~ 1.5) and default to 1.0

Fix memory corruption in TGlslIoMapper

Use NOT ... VERSION_LESS instead of VERSION_GREATER_EQUAL

Use correct enum type in case statement

Two similarly named enums led to the wrong one being used here, this
is getting caught in the Chromium and Dawn DEPS rolls.

Revisit fix for #2062 for consistency with this commit.

Fix for GCC 9 / Werror=deprecated-copy

Add Tess machine dependent built-in variables initialization for GLES…

Implemented C-language interface for glslang

Add Error check flag in io mapper

GLSL could detect contradictory uniform binding, but missing error reporting, even if we could now observe error inside infosink.

Add error check when first time validate uniform binding. When doing traversal, it should be zero error.

This error check flag will be used during linking time. To quickly report errors like contradictory uniform bindings.

Add error check flags for TDefaultGlslIoResolver when catching EPrefixInternalError

SPV/Vulkan: Add support for Vulkan 1.2, which defaults to SPIR-V 1.5.

Fix glslang can't link multiple AST in a single stage

Add support for ARB_gpu_shader_fp64

Fix #1829: Allow "--" options for def/undef, for OpModuleProcessed.

This allows OpModuleProcessed logging to be consistent with everything taking
"--" options.

FYI, move builtin check to type symbol check.
Avoid modifying interface doubleCheck().

Add missing extension defination

This micro should been defined 1, if opengl 2.0 is required.

Modify max binding checks for atomic_uint

Add builtin constants gl_MaxFragmentUniformVectors and gl_MaxVertexUniformVectors.

Add builtin constants:

gl_MaxFragmentUniformVectors and gl_MaxVertexUniformVectors.
They should both be available since version 410 for core.

GLSL Version : >= 150

Add support for implicit conversion

1. Remove builtin double vertex (this is introduced by vertex_attrib_64bit
2. Add extension check and implicit conversion as double has been introduced
3. Add test results.
