[PATCH] D30572: Remove equal BBs from a function

[Andrew V. Tischenko via Phabricator via llvm-commits]

I implemented requirements raised by Davide and fix an issue with bootstrap: now it works properly. Next steps: I'm going to collect statistic on bootsrap such as: number of removed BBs and instructions inside those BBs, the total size changing, compile time. When it's done I'm going to extend transformation with other kinds of BBs (e.g. parts of EH, -O1 (size) optimizations) and/or terminators.
