Thanks Richard for the detailed comments/code pointers! I've switched to
using MO_ALIGN_16 and implemented record_sigbus and do_unaligned_access
hooks to simulate #GP(0) as suggested. Given what was said about the low
likelihood of implementing #AC anytime soon, I have hardcoded #GP(0) in
these hooks for now rather than plumbing through an extra bit in MemOp.
Let me know if that seems reasonable, thanks!
