* arm.c (adjacent_mem_locations): Reject volatile memory refs.
Also reject cases where this pattern will cause load delay stalls
unless optimizing for size and it will produce a shorter sequence.
* arm.md (arith_adjacent_mem): Make better use of ldm addressing
variants to avoid pre-adjusting the base when possible.
