2067d1a93e Add test case for read-only storage texture passed to helper function (#2414) 
This is based on spv.paramMemory.frag.out which exercises the
writeonly storage image case.

This appears to need desktop GLSL.

The generated SPIR-V fails validation because the image_write function
takes a parameter which is pointer to an OpTypeImage with Unknown format.
But the parameters passed in are pointer to OpTypeImage with formats Rgba32f
and Rgba16f. The validator rejects this, saying the parameter types must
match.

fe24a54808 Non-determinism: Remove test file that seems to trigger non-determinism. 
This problem needs to be fixed, but in parallel, we need to see master
and any other changes to it passing all tests.

The removed test is ray-tracing centric, and may indicate non-determinism
in recent code added for that functionality.

12c155f303 SPV: RelaxedPrecision: use the result precision for texture sampling. 
Fix #2298.

The AST has two precisions, an operation precision and a result precision.
Actual use of GLSL with mediump samplers wants the result precision, so
pick that up instead of the operation precision.

4df10335e6 SPV: Partially address #2293: correct "const in" precision matching. 
Track whether formal parameters declare reduced precision and match
that with arguments, and if they differ, make a copy to promote the
precision.

ff6dcca575 spirv: Support initializers on uniforms (#1588) 
If a uniform has an initializer it will now be given as the optional
initializer operand to the OpVariable instruction.

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.

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.
