When we'd originally added unaligned-scalar-mem and unaligned-vector-mem, they were separated into two parts under the theory that some processor might implement one, but not the other. At the moment, we don't have evidence of such a processor. The C/C++ level interface, and the clang driver command lines have settled on a single unaligned flag which indicates both scalar and vector support unaligned. Given that, let's remove the test matrix complexity for a set of configurations which don't appear useful.
Given these are internal feature names, I don't think we need to provide any forward compatibility. Anyone disagree?
Note: The immediate trigger for this patch was finding another case where the unaligned-vector-mem wasn't being properly serialized to IR from clang which resulted in problems reproducing assembly from clang's -emit-llvm feature. Instead of fixing this, I decided getting rid of the complexity was the better approach.
