X86 did not support any of the intrinsics, and the X86 test case did not even call `getPredicateForOption`. The call to `getPredicateForOption` was added in f2e9b827d699115f8683e9def06c249e5476fd50, and since then all the cases are the same.

I'd like to merge this early next week; if anyone still wants to review this but needs more time, please leave a note.
