This patch changes the way we search symbols when fixing up a stack.
Previously we would find the closest PUBLIC or FUNC entry lower than a given
address. Because of how symbol files were processed we preferred PUBLIC
entries to FUNC ones. Now we look first for the function that contains the
address (obtained from the FUNC entries) then if none is available we look for
the closest, lower PUBLIC entry.
