I'll experiment a bit to see if there's some way to separate out the legalization changes; the llvm.experimental.vector.extract tricks I figured out for D106028 <https://reviews.llvm.org/D106028> might be usable for that.  The rest is sort of tied together.

There isn't an explicit dependency.  The SplitVecRes_INSERT_SUBVECTOR here is a less general version of the one in D106028 <https://reviews.llvm.org/D106028>.
