In this case, our planned transition to generic unaligned SSE loads should
"fix" this issue. The realignment will be necessary only for performance
reasons, not for the correctness. Maybe we should also look if
SLOW_UNALIGNED_ACCESS affects moves that may result in muvups insns.

(However, since movups from unaligned address is slow, I still think that
realignment should be fixed for STV pass).
