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.
