    RISC-V: Add vectorized strcmp and strncmp.

    This patch adds vectorized strcmp and strncmp implementations and
    tests.  Similar to strlen, expansion is still guarded by
    -minline-str(n)cmp.

    gcc/ChangeLog:

            PR target/112109

            * config/riscv/riscv-protos.h (expand_strcmp): Declare.
