What's the proper way to remove something from llvm.used? I tried RAUW
undef but that did not go over well. 
Is it best to delete it and
re-create it with only the remaining items?

Generally you shouldn’t do so: attribute((used)) means that a declaration is used in a way that is unknown to the compiler, so the compiler should keep the thing around unchanged.

Yes, that would be the correct way to update the list.
