Thinking about it, alternative behaviours can be:
1) make compiler to only forward inline when function overwrites builtin
   (100% compatible with current code)
2) make compiler to never inline when function overwrite builtin
   (consistent, but will break glibc and kernel headers at least)

What I am doing right now is to overwrite builtin by function only when
function will inline that is also too consistent.  In case 1) or 2)
is way to go, I can revert the *-opt.c part of the patch.
