    i386: Fix up cond_{and,ior,xor,mul}* [PR104779]

    The following testcase ICEs, because the cond_andv* expander
    has vector_operand predicates in both of the commutative inputs
    and calls gen_andv*_mask which calls ix86_binary_operator_ok
    in its condition, but nothing calls ix86_fixup_binary_operands_no_copy
    during the expansion, which means cond_* accepts even operands
    like 2 MEMs which then can't be matched.

    The following patch handles it like most other insns that the other
    cond_* patterns use - by having a separate define_expand that calls
    ix86_fixup_binary_operands_no_copy and define_ins with
    ix86_binary_operator_ok.
