re PR target/88547 (missed optimization for vector comparisons)

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.
