Time trace prototype

So I've just created a prototype patch, but I don't see it much useful:
https://gist.github.com/marxin/dc4354696bc5bd76cdc1d2ecaa4ab060

The main problem is that in case of tree/RTL passes, we run each pass for each
function. Which makes the report full of thin lines.
Thoughts?
