[PATCH] D29998: Add initial support for debug counting

[Daniel Berlin via Phabricator via llvm-commits]

dberlin added a comment.

A few notes:

1. I have scripts that automate binary searching the counters that i'll

upload at some point.

My current scripts only binary search a single counter, but actually, if your
miscompile requires multiple transforms, you can binary search all the
counters.

2. Not sure what to do about counter registration.

It's easy for passes, i think.
For utilities, right now you have to just create a static object that calls registerCounter.

Right now, nothing prints the list of counters.

I could set up some macros like we have STATISTIC to register them, if folks think that is the right approach.
