RISC-V: fix expand function of vlmul_ext RVV intrinsic

Consider this following case:
void test_vlmul_ext_v_i8mf8_i8mf4(vint8mf8_t op1) {
  vint8mf4_t res = __riscv_vlmul_ext_v_i8mf8_i8mf4(op1);
}

Compilation fails with:
test.c: In function 'test_vlmul_ext_v_i8mf8_i8mf4':
test.c:5:1: error: unrecognizable insn:
    5 | }
      | ^

gcc/ChangeLog:

	* config/riscv/riscv-vector-builtins-bases.cc: change emit_insn to
	emit_move_insn

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/base/vlmul_ext-2.c: New test.
