RISC-V: Add test for vec_duplicate + vrsub.vv combine case 1 with GR2VR cost 0

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-4-i16.c: Add asm check
	for vrsub case 1 with GR2VR cost 0.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-4-i32.c: Ditto.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-4-i64.c: Ditto.
