    fold-const: Handle AND, IOR, XOR with stepped vectors [PR112971].

    Found in PR112971 this patch adds folding support for bitwise operations
    of const duplicate zero/one vectors with stepped vectors.
    On riscv we have the situation that a folding would perpetually continue
    without simplifying because e.g. {0, 0, 0, ...} & {7, 6, 5, ...} would
    not be folded to {0, 0, 0, ...}.

    gcc/ChangeLog:

            PR middle-end/112971

            * fold-const.cc (simplify_const_binop): New function for binop
            simplification of two constant vectors when element-wise
            handling is not necessary.
            (const_binop): Call new function.

    gcc/testsuite/ChangeLog:

            * gcc.target/riscv/rvv/autovec/pr112971.c: New test.
