commit 8f91e6426176ce0309517ed9614dd125f380da52
Author: Michael Meissner <meissner@linux.ibm.com>

    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.

            instead of altivec_register_predicate.
