    RISC-V: Bugfix for ICE in block move when zve32f

    The exact_div requires the exactly multiple of the divider.
    Unfortunately, the condition will be broken when zve32f in
    some cases. For example,

    potential_ew is 8
    BYTES_PER_RISCV_VECTOR * lmul1 is [4, 4]

    This patch would like to ensure the precondition of exact_div
    when get_vec_mode.

            PR target/112743

    gcc/ChangeLog:

            * config/riscv/riscv-string.cc (expand_block_move): Add
            precondition check for exact_div.

    gcc/testsuite/ChangeLog:

            * gcc.target/riscv/rvv/base/pr112743-1.c: New test.
