Fix xxeval predicates (PR 99921).
I noticed that the xxeval built-in function used the altivec_register_operand
predicate. Since it takes vsx registers, this might force the register
allocate to issue a move when it could use a traditional floating point
register. This patch fixes that.

* config/rs6000/altivec.md (xxeval): Use register_predicate
instead of altivec_register_predicate.
