RISC-V: Add test for vec_duplicate + vrsub.vv combine case 1 with GR2VR
cost 2
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.target/riscv/rvv/autovec/vx_vf/vx-6-i16.c: Add asm check
for vrsub with GR2VR cost 2.
