Something "cheap" we could do is attach nonnull attributes to arguments of inlined calls, when appropriate.

llvm.assume is fundamentally pretty expensive; it bloats use-lists, and there's additional instructions feeding into the assume.  There are some aspects we could make cheaper with an optimized form of llvm.assume, but it's not easy.
