RISC-V: Fix incorrect use of vcompress in permutation auto-vectorization
This patch fixes following FAILs on zvl512b of RV32 system:
FAIL: gcc.target/riscv/rvv/autovec/struct/struct_vect_run-12.c execution test
FAIL: gcc.target/riscv/rvv/autovec/struct/struct_vect_run-9.c execution test
The root cause is that for permutation indice = {0,3,7,0} use vcompress optimization
which is incorrect. Fix vcompress optimization bug.
PR target/112598
gcc/ChangeLog:
* config/riscv/riscv-v.cc (shuffle_compress_patterns): Fix vcompress bug.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/pr112598-3.c: New test.
