435dd8028b SPV: RelaxedPrecision: Generalize fix #2293 to cover more operations. 
This simplifies and enforces use of precision in many more places,
to help avoid accidental loss of RelaxedPrecision through intermediate
operations. Known fixes are:
- ?:
- function return values with mis-matched precision
- precision of function return values when a copy was needed to fix types

bbbd9a2a1f Fix #1843: Handle built-in function output parameters to a swizzled arg 
In GLSL/HLSL/AST,  v.zyx is an l-value, but not in SPIR-V, which cannot represent it.
So, a temporary is used instead.

e43e8ba9f3 SPIR-V postprocessing: WEB case only needs CFG mods 
The SPIR-V post-processing to discover capabilities and
extensions does not apply to WebGPU compilation.  So don't include
that code.

This reclaims some of the code space added by #1943

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.

ee8e9c1522 Fix #1924: Promote SPV_EXT_physical_storage_buffer to KHR when required. 
If the semantics that require the KHR form over the EXT form are seen
(OpBitcast between a vector and a pointer) promote the requested extension
from the EXT to the KHR.

8317e6c683 SPV: Support SPIR-V 1.5; five extensions no longer need OpExtension.

f04c51b3bd Non-Functional: Add postprocess as more robust way to add capabilities 
When capabilities are needed for specific SPIR-V instructions, it is
fragile to do so based on GLSL/AST usage; it should be based on actual
instructions they got translated to.

eddb1318ae Use the correct type for the constant for matrix/scalar division 
When a matrix is divided by a scalar it tries to take the reciprocal
of the scalar to convert the operation into a multiply. However it was
always doing this by making a 32-bit constant. If the scalar is a
double then this would end up making an FDiv instruction with
different types in the operands.

This patch adds a helper method called makeFpConstant which makes a
floating-point constant of the given type. The code to take the
reciprocal now uses it to make the same type as the result.

46413d5780 SPV: Fix #1258: cache constant structs by id, not opcode. 
Constants were generally cached by type opcode, but all structures share the
same type opcode (OpTypeStruct), so they need to be cached by type id.
