7e8afa872b Implement OpSpecConstantOp. 
The details here get quite hairy, and it's not complete as not all
functionality is implemented in glslang yet.

706d3ead29 Always run spirv-val for SPIR-V files created. 
Add way to disable testing if SPIR-V is not validating properly.

042475e88e Add support for multiple entry points. 
- Only consider I/O variables if part of OpEntryPoint.
- Keep a safe fallback if #entry-points is 1 to avoid potentially
  breaking previously working shaders.

36a0b63f28 Fix various corner cases with expression dependencies. 
There was a potential problem if variables were invalidated and SPIR-V
read expressions which depended on other expression which in turn depended on the
invalidated variable.

Also fixes issue where variables were considered immutable if they were
forwardable. This allowed some incorrect optimizations to slip through.

168e46fdf9 Use std::array in C++ backend. 
Deals better with composite construction in C++
and also fixes a few bugs in GLSL backend with array-of-arrays.

4739d16e98 Remove workaround for overly conservative memory barriers. 
This is now fixed in ESSL 3.10 backend of glslang, so we can remove the old workaround
of dropping full memory barriers.

Also fixes unrelated issue which newer glslang detects.

5ad4340976 Workaround case with identical structs but different types. 
With the current workarounds for SSBO type aliasing, we have no choice
but to look at OpName in order to figure this out properly.

6aa2007cba Deal better with OpName and OpMemberName which alias. 
OpName is only for debug information, so we must be very careful that
we do not reuse the same name for different variables.

This was previously done for local variables, but this commit extends
this to global variables as well.

45ad58a903 Implement more correct integer op handling. 
In some cases we need to bitcast when dealing with int vs. uint.
SPIR-V allows inputs to be of different integer signedness, so we need
to deal with this somehow.

Add testing system to test SPIR-V assembly.
For now, test all possible combination for all major cases.

 - IAdd (which doesn't care about input type as long as they're equal)
 - SDiv/UDiv operations which case about input type.
 - Arith/Logical right shifts.
 - IEqual to test outputs to bvec, which shouldn't get output cast. Also
   tests casting in function-like calls.

2d38c6e192 Fixups for struct-packing test. 
There seems to have been some changes to alignment in glslang here,
so workaround to verify that the other cases at least still work as expected.

ba0ab875c8 Fix cases where SPIR-V conditionally branches to loop headers. 
We should check if we are actually branching back to loop header.
Fixes some logic when continue_block == loop_header.
