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.
