Fix xxeval predicates.
In doing the patch to move the XX* built-in functions from altivec.md to
vsx.md, 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/vsx.md (xxeval): Use register_predicate instead of
altivec_register_predicate.
