Also as a note.
I doubt using native compilation with LTO could bring measurable
advantages.
All the Emacs C primitives we call from elns have a function pointer
indirection as they can be redefined, so GCC can't inline them. Few
support functions are called directly but I would be surprised of any
measurable effect there.
