This removes the Y constraint from the tabort pattern definition. In
this case it is easier without using substitutions.
gcc/ChangeLog:
2016-01-14 Andreas Krebbel <kreb...@linux.vnet.ibm.com>
* config/s390/s390.md ("*tabort_1"): Change predicate to
addrreg_or_constint_operand. Add a second alternative to cover
register as well as const int operands.
("*tabort_1_plus"): New pattern definition.
