To get around a major problem with the FE (4.0) and the alignment of src & dest
pointers to a memcpy, we default the alignment to 1 in all cases. This is a
hack and we should find a real fix for this. Basically, both the src & dest
pointers' alignments need to be taken into account when generating the
alignment for the memcpy; picking the smallest alignment.
