Not ever access does so. There are only 3 memory related calls to check_align.
The other three are for indirect branches.
For the 8 byte memory operations we can just remove the checks. There, the
softmmu operation checks the alignment. For usermode, we've typically ignored
the guest alignment (which also causes failures for a host that requires
alignment emulating a guest that does not).
