8c3d5b4b6c SPIR-V: Aggressively prune unreachable merge, continue target 
More aggressively prune unreachable code as follows.
When no control flow edges reach a merge block or continue target:
- delete their contents so that:
  - a merge block becomes OpLabel, then OpUnreachable
  - a continue target becomes OpLabel, then an OpBranch back to the
    loop header
- any basic block which is dominated by such a merge block or continue
  target is removed as well.
- decorations targeting the removed instructions are removed.

Enables the SPIR-V builder post-processing step the GLSLANG_WEB case.

b9197c812e Web: Make switched methods all be non-virtual, more web-dependent code, 
added a few more HLSL flag tests.  This was mostly focused on the SPV generator.
Saves about 17K.

7015bd658e Web: Remove/rationalize a set of *_EXTENSIONS, using GLSLANG_WEB. 
Focus was on the front end (not SPIR-V), minus the grammar.
Reduces #ifdef count by around 320 and makes the web build 270K smaller,
which is about 90% the  target size.

The grammar and scanner will be another step, as will the SPIR-V backend.
This makes heavy use of methods #ifdef'd to return false as a global way
of turning off code, relying on C++ DCE to do the rest.

faac86e5d6 If a shader's only use of float16 is for FConvert, add the Float16 capability. 
When visiting instructions, check that there are no 16-bit storage capabilities
and add the Float16 capability. Same for int8/int16.

83170e3f7a Enable GL_KHR_shader_subgroup properly 
(and GL_NV_shader_subgroup_partitioned) based on GL/ES version
instead of predicating it on vulkan SPV generation

Also add AST testing.
The glsl.450.subgroup* files are largely the same as the spv.subgroup*
The glsl.es320.subgroup* files are the same as the 450 versions, but modified to be ES compatible.

be63facd80 Handle buffer references vs 'const' 
Allow constructors to and from references to be constant folded. Section 4.3.3
says constructors whose arguments are all constant expressions must fold.

Disallow 'const' on buffer reference types. It is not a 'non-void transparent
basic data type' (it is not considered 'basic').

Handle buffer reference constants (which can be assigned to a non-const reference,
or can be further folded to another type of constant) by converting to
'constructor(uint64_t constant)' in addConversion.

Disallow == and != operators on reference types.
