Fix builtins for GL_EXT_shader_explicit_arithmetic_types for es

Issue error when declaration rule fails

Add IntLog2 and use it

Replace uses of floating point log2 when we want an integer result from
an integer operand.  This avoids concerns about accuracy of floating
point library functions.

Get rid of extra semicolon causing gcc 10.3 troubles.

Removed condition for glslang-default-resource-limits instalation.

Fix table key and whitespace

These got lost in the wash with my last revert but are still relevant.

Fix #2514.

Add setter for TInterimSelection.condition

This way the limits are available to clients that links statically.

Revert "Update minimum SPIR-V requirement for GL_EXT_buffer_reference"

Do not propagate packing qualifiers to scalars or vectors

Packing qualifiers have no practical effect on scalars or vectors
so this is unnecessary and its confusing tools downstream that
consume the AST.

Update minimum SPIR-V requirement for GL_EXT_buffer_reference

Fix SPIR-V for HLSL EvaluateAttribute* of interpolants in structs

Generate load of interpolant for first operand to GLSLstd450
InterpolateAt* SPIR-V ops. This allows the interpolants to
propagate from the input struct in the wrapper around main
into the shader during HLSL legalization. A new pass has been
added to legalization which will remove the load and replace
with the pointer of the load to create valid external
interpolate op.

Fixes #2584

For bug #2580: sparseTextureGatherOffsetsARB should only take constant offsets

Require SPIR-V 1.3 when using GL_EXT_buffer_reference.
Migrate tests to SPIR-V 1.3 fixture as necessary.
Fix extension table key.
Fix whitespace.

Fix warnings about int comparisons of different signness

Warnings in public headers can trigger warnings-as-errors.

Default to KHR extension

Don't check precision qualifiers on cross-stage checks

Fix #2530.

Fixes #2586

Add cmd_bat action to bazel export_spirv_headers target

Fixed OpGroupNonUniformQuadBroadcast Direction operand being marked as a literal

Only having `cmd` rather than separate `cmd_bash` and `cmd_bat` (or
`cmd_ps`) requires bash to be installed on Windows. So adding support
for `cmd_bat` makes glslangValidator easier to compile on Windows.

Partial fix for inconsistencies re: #2578

gl_SecondaryPositionNV and gl_PositionPerViewNV are inconsistently
declared inside and outside of gl_PerVertex. This breaks interface block
matching. For now ignore these errors since it should be fixed with how
they are declared.

Fix issue with remapping global uniform blocks

fix typo for u64vec2/3/4 type define value

Avoid adding global uniform blocks to stages that don't already have it.
Otherwise multiple stages point to the same block object, and a
remapping that occurs later on will change the mapping on multiple
stages.
