--- Comment #10 from Chandler Carruth <chandlerc at gmail.com> ---
And the last obvious and easy to fix quadratic behavior is fixed in r207409.
The code is still quite slow to compile (25 seconds in opt for me) but
overwhelmingly this is due to slowness in LVI and jump threading that are
reasonably well known and lang standing. I don't have a bug handy, but I don't
know that this bug is tracking anything interesting at this point.

Thanks for the original report! Lots of great fixes stemming from that!
