How could you avoid the arm.c changes from my patch if you are using rtx_equal
on the MEM's addr and first operand of PLUS?  I believe either that arm.c
change is needed, or the predicate used on the new define_insns needs to repeat
the analysis done in gen_operands_ldrd_strd - verify that the two MEMs are 4
bytes appart (just, unlike gen_operands_ldrd_strd, require that the first one
is before second one).
