    Rename ufix_trunc/ufloat* patterns to fixuns_trunc/floatuns* to align with
standard pattern name.

    There's some typo for the standard pattern name for unsigned_{float,fix},
    it should be floatunsmn2/fixuns_truncmn2, not ufloatmn2/ufix_truncmn2
    in current trunk, the patch fix the typo, also change all though
    ufix_trunc/ufloat patterns.

    Also vcvttps2udq is available under AVX512VL, so it can be generated
    directly instead of being emulated via vcvttps2dq.
