RISC-V: Add test for vec_duplicate + vrsub.vv combine case 0 with GR2VR
cost 1
Add asm dump check test for vec_duplicate + vrsub.vv combine to vrsub.vx
The below test suites are passed for this patch.
* The rv64gcv fully regression test.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/rvv/autovec/vx_vf/vx-2-i16.c: Add vrsub asm
dump check.
* gcc.target/riscv/rvv/autovec/vx_vf/vx-2-i32.c: Ditto.
