Nick Lewycky 65a0af3855 Fix an infinite loop; merging two functions will create a new function (if the
two are weak, we make them thunks to a new strong function) so don't iterate
through the function list as we're modifying it.

Also add back the outermost loop which got removed during the cleanups.
