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.

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.

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.

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.

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.

so workaround to verify that the other cases at least still work as expected.
