S/390: Get rid of Y constraint in tabort.

This removes the Y constraint from the tabort pattern definition.  In
this case it is easier without using substitutions.

gcc/ChangeLog:

2016-03-01  Andreas Krebbel  <krebbel@linux.vnet.ibm.com>

	* config/s390/s390.md ("*tabort_1"): Change predicate to
	nonmemory_operand.  Add a second alternative to cover
	register as well as const int operands.
	("*tabort_1_plus"): New pattern definition.
