efriedma added a comment. I think the worst of the backend issues with vectors of non-byte-size integers have been resolved? Work on that has progressed slowly for a very long time. There have been a constant stream of issues. (See, for example, D129164 <https://reviews.llvm.org/D129164>.) But LangRef does define the memory layout, and CodeGen does essentially implement that layout.
It's not clear to me we actually want to use that layout for vectors of non-power-of-two types. Load/store for bit-packed vectors isn't efficient. Maybe we can just enable this specifically for types which are a power of two multiple of 8 for now (where there's one obvious layout), and consider the other cases later?
