[PATCH] D12543: [x86] fix allowsMisalignedMemoryAccesses() for 8-byte and smaller accesses

lgtm..

The overlapping is interesting.. With a 0 mod 16 rsp, if we didn't overlap, we would split a cache line. At a high level, it looks like it's a reasonable strategy (without knowing all the cases in which it'll trigger). The extra immediate generation is, however, weird.

Thanks,
Zia.
