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.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-2-i64.c: Ditto.
	* gcc.target/riscv/rvv/autovec/vx_vf/vx-2-i8.c: Ditto.
