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.
