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.

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.

Add support for Vulkan GLSL as output target.
...
Mostly useful for debugging SPIR-V where it is useful to see the
"original" Vulkan GLSL constructs which created the SPIR-V.

Use texel fetch instead of normalized sampling for subpass.
...
Cleaner output code, and matches more directly to how subpass reads work.

Add support for separate samplers and textures.
...
This will not really make sense for plain GLSL/ESSL target, but other
backends might want it and useful to have for debugging.

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.
