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.
* config/riscv/riscv-string.cc (riscv_expand_strcmp): Add
strategy handling and delegation to scalar and vector expanders.
(expand_strcmp): Vectorized implementation.
* config/riscv/riscv.md: Add TARGET_VECTOR to strcmp and strncmp
expander.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/builtin/strcmp-run.c: New test.
* gcc.target/riscv/rvv/autovec/builtin/strcmp.c: New test.
* gcc.target/riscv/rvv/autovec/builtin/strncmp-run.c: New test.
* gcc.target/riscv/rvv/autovec/builtin/strncmp.c: New test.
