Patch without testcase

I've bootstrapped the attached patch on s390 and s390x without 
testsuite regressions.
The patch matches almost exactly what you did. Additionally
I've merged the predicates setmem_operand and shift_count_operand
because after that change they contain the same code.
And the setmem_long pattern should as well be duplicated checking
for a mask of 255.
As testcase I think the smaller testcase I posted would be preferable.
