    i386: Disable SImode/DImode moves from/to mask regs without avx512bw
[PR118067]

    SImode and DImode moves from/to mask registers are valid only with
AVX512BW,
    so mark relevant alternatives in *movsi_internal and *movdi_internal as
such.

            PR target/118067

    gcc/ChangeLog:

            * config/i386/i386.md (*movdi_internal):
            Disable alternatives from/to mask registers without AVX512BW.
            (*movsi_internal): Ditto.
