Stabilize inliner
The Fibonacci heap can change its behaviour quite significantly for no good
reasons when multiple edges with same key occurs. This is quite common
for small functions.
This patch stabilizes the order by adding edge uids into the info.
Again I think this is good idea regardless of the incremental WPA project
since we do not want random changes in inline decisions.
