    i386: Fix up *<dwi>3_doubleword_mask [PR105911]

    Another regression caused by my recent patch.

    This time because define_insn_and_split only requires that the
    constant mask is const_int_operand.  When it was only SImode,
    that wasn't a problem, HImode neither, but for DImode if we need
    to and the shift count we might run into a problem that it isn't
    a representable signed 32-bit immediate.

    But, we don't really care about the upper bits of the mask, so
    we can just mask the CONST_INT with the mode mask.
