[x86] fix allowsMisalignedMemoryAccesses() for 8-byte and smaller accesses
This is a continuation of the fix from:
http://reviews.llvm.org/D10662
and discussion in:
http://reviews.llvm.org/D12154
Here, we distinguish slow unaligned SSE (128-bit) accesses from slow unaligned
scalar (64-bit and under) accesses. Other lowering (eg, getOptimalMemOpType)
assumes that unaligned scalar accesses are always ok, so this changes
allowsMisalignedMemoryAccesses() to match that behavior.
