sorry, I think I mislead you, having a target independent test is not a bad idea, and I am not against.

 I think that having a full coverage in the AArch64 tests would be still good, as we can cover the scalable case, which can not be covered in the target independent tests, the _LLVM_ won't allow to add mappings for scalable vectors.
