        * config/rs6000/predicates.md (invert_fpmask_comparison_operator):
        New predicate that matches the ISA 3.0 XSCMP{EQ,GT,GE}DP
        instructions when you want to invert the test.
        * config/rs6000/rs6000.md (fpmask<mode>): Use the arguments in the
        correct order for XXSEL.
        (mov<SFDF:mode><SFDF2:mode>cc_invert_p9): Define the inverted test
        for using XSCMP{EQ,GT,GE}DP.
