>> But we should have this after we filter out the annotations from memcpy/memset (etc.) in Clang (when the size is dynamic or zero)

I dont think we want add/remove attributes in Clang based on size argument. It seems just bad to look at function names in Clang and go thru Clang AST to inspect size argument.

Either drop all and possibly add it back here in instcombine or leave it and drop it in eg. BuildLibCalls?
