Add a vect_unaligned_possible target selector
This patch adds a target selector that says whether we can ever
generate an "unaligned" accesses, where "unaligned" is relative
to the target's preferred vector alignment. This is already true if:
vect_no_align && { ! vect_hw_misalign }
i.e. if the target doesn't have any alignment mechanism and also
doesn't allow unaligned accesses. It is also true (for the things
tested by gcc.dg/vect) if the target only wants things to be aligned
to an element; in that case every normal scalar access is "vector aligned".
