RISC-V: Refactor the testcases for RVV gather/scatter

This patch would like to refactor the testcases of gather/scatter
after sorts of optimization option passing to testcase.  Includes:

* Remove unnecessary optimization options.
* Adjust dg-final by any-opts and/or no-opts if the rtl dump changes
  on different optimization options (like O2, O3).

The below test suites are passed for this patch.
* The rv64gcv fully regression test.

It is test only patch and obvious up to a point, will commit it
directly if no comments in next 48H.

gcc/testsuite/ChangeLog:

	* gcc.target/riscv/rvv/autovec/gather-scatter/gather_load_64-12-zvbb.c:
	Adjust the dump check times.
	* gcc.target/riscv/rvv/autovec/gather-scatter/strided_load-1.c:
	Remove unnecessary option and add target no-opts/any-tops.
	* gcc.target/riscv/rvv/autovec/gather-scatter/strided_load-2.c: Ditto.
	* gcc.target/riscv/rvv/autovec/gather-scatter/strided_store-1.c: Ditto.
	* gcc.target/riscv/rvv/autovec/gather-scatter/strided_store-2.c: Ditto.
