Feature request: show all refs from which a commit is reachable on /+/<hash> pages

Go to a commit's page, like <gitiles host>/+/<hash>.

It's hard to tell what branches that commit might be on. You have load the +log 
pages for those refs, and then ctrl-f for the hash.

In command-line git, it is comparatively easy: you can run a merge-base, or a 
log --graph. Since Gitiles has neither of those features, it would be really 
cool to have a div (probably collapsed by default) which lists all of the refs 
from which the current commit is reachable.
