    x86: yet more PR target/100711-like splitting

    Following two-operand bitwise operations, add another splitter to also
    deal with not followed by broadcast all on its own, which can be
    expressed as simple embedded broadcast instead once a broadcast operand
    is actually permitted in the respective insn. While there also permit
    a broadcast operand in the corresponding expander.
