I want to get back to this after addressing a few related things. My main worry is that this is only useful with LTO because the linker should do this work otherwise, so at a minimum I need to change the code accordingly. I'm working on other ways to achieve the size wins I want, and then I'll fiddle with LTO to see how much can be done.
