bfc21ff1a9 Web: Change a bunch of HLSL methods from dynamic to compile-time known. 
This saves about 7K.
By changing just a few methods to be compile-time known, a bunch of
scattered code becomes DCE.

07ef0e4c84 For GL_NV_geometry_shader_passthrough extension, the Inferred output primitive for ElgTriangles should be ElgTriangleStrip. 
Also removed unnecessary relax for GL_NV_geometry_shader_passthrough in link validate

035cbbe3d0 Allow redeclaration of builtin interface blocks in mesh shader 
Apart from allowing redeclaration of gl_MeshPerVertexNV and gl_MeshPerPrimitiveNV blocks, this change also -
- Resize clip/cull perview distances based on static index use
- Error out use of both single-view and per-view builtins
- Add new gtests with redeclared blocks and edit existing test output
- Fix couple of typos

41436ad204 Link/SPV: Correct symbol IDs on merging ASTs to a single coherent space 
This is one step in providing full linker functionality for creating
correct SPIR-V from multiple compilation units for the same stage.
(This was the only remaining "hard" part. The rest should be simple.)

ead8622484 Non-functional. Rationalizations enabling future generalizations: 
- Use much simpler method to update implicit array sizes.
  The previous overly complicated method was error prone.
- Rationalize all use of unsized arrays.
- Combine decorations when generating SPIR-V, to simplify
  adding extensions.

2d53904999 Take into account the number of locations taken up by a uniform 
When assigning uniform locations it now takes into account the number
of locations occupied by the type. For uniforms, all types except
arrays and structs take up one location. For arrays the base location
count is multiplied by the array dimensions and for structs it is the
sum of the locations of each member.

c5215791f5 IO mapper: Fix #1261: Supply location mapper with size computer. 
This factored computeTypeLocationSize() out of needing the TIntermediate contents,
and uses it to show how to know how many locations an object needs.
However, it still does not do cross stage, or mixed location/no-location
analysis.

- Add int16 support to GLSL operators.
- Add int16 type conversions (to int16, from int16).
- Add int16 built-in functions.

71facdf435 SPV: Give error on not assigning locations to I/O. 
Also, provides an option to auto-assign locations.
Existing tests use this option, to avoid the error message,
however, it is not fully implemented yet.

e741249b72 HLSL: pass tessellation execution modes through to SPIR-V 
The SPIR-V generator had assumed tessellation modes such as
primitive type and vertex order would only appear in tess eval
(domain) shaders.  SPIR-V allows either, and HLSL allows and
possibly requires them to be in the hull shader.

This change:

1. Passes them through for either tessellation stage, and,

2. Does not set up defaults in the domain stage for HLSl compilation,
to avoid conflicting definitions.

4b6ce415ef GLSL Linker: Track entry point across compilation units. 
This wasn't needed until the recent generalization of "main" to "entry point",
so makes some HLSL-specific code be generic now, for GLSL functional correctness.
