I noticed I had assumed AArch64 was available in the unittests, so I updated those to be skipped in the case where it isn't.

@arsenm what do you mean is impossible? These appear to be some of the first unittests for SelectionDAG, but I don't see how to test these cases without adding them. Even if there is a reason not to add them, I still can't add more IR tests for the remaining cases.
