    target/123027 - handle min/max expansion when -ffinite-math-only

    When we get a <= b ? b : a into ix86_expand_sse_fp_minmax we can
    swap and invert this with -ffinite-math-only to get a < b ? a : b.

            PR target/123027
            * config/i386/i386-expand.cc (ix86_expand_sse_fp_minmax):
            With !HONOR_NANS we can handle LE by swapping and inverting.

            * gcc.target/i386/pr123027.c: New testcase.
            * gcc.dg/torture/pr123027.c: Likewise.
