Apparently, we are missing vrsub.vi tests.

gcc/testsuite/ChangeLog:

        * gcc.target/riscv/rvv/autovec/binop/vsub-run.c: Add vsub.vi.
        * gcc.target/riscv/rvv/autovec/binop/vsub-rv32gcv.c: Ditto.
        * gcc.target/riscv/rvv/autovec/binop/vsub-rv64gcv.c: Ditto.
        * gcc.target/riscv/rvv/autovec/binop/vsub-template.h: Ditto.
