    i386: Fix k*shift* intrinsics [PR93673]

    As mentioned in the PR, the intrinsics allow counts from 0 to 255, but
    we actually reject values from 128 to 255.  That is because QImode
    CONST_INTs can be only -128 to 127.  Fixed by using const_0_to_255_operand
    and dropping the modes for the operands with those predicates
    (the IL actually contains the CONST_INT which has VOIDmode).

        * config/i386/sse.md (k<code><mode>): Drop mode from last operand and
        use const_0_to_255_operand predicate instead of immediate_operand.
