S/390: Use define_subst for the setmem patterns.
While trying to get rid of the Y constraint in the setmem patterns I
noticed that for these patterns it isn't even a problem since these
always only use the constraint with a Pmode match_operand. But while
being at it I've tried to fold some of the patterns a bit.
