The destination parameter is still needed as the computation requires
so.

The default policy for non-policy (implicit) vslideup intrinsics
will be tail agnostic and mask undisturbed.

This is the 4th commit of a patch-set that aims to remove the
IsPrototypeDefaultTU special case for the rvv-intrinsics.

Please refer to the cover letter in the 1st commit (D140895 <https://reviews.llvm.org/D140895>) for an overview.
