Log:
        PR target/88547
        * config/i386/i386.c (ix86_expand_sse_movcc): For maskcmp, try to
        emit vpmovm2? instruction perhaps after knot?.  Reorganize code
        so that it doesn't have to test !maskcmp in almost every conditional.

        * gcc.target/i386/pr88547-1.c: New test.
