Another patch in the general direction of http://lists.cs.uiuc.edu/pipermail/llvmdev/2014-February/070242.html
Separates some utility functions from opt.cpp into a separate module, currently still within tools/opt. The idea is to enable custom opt-like tools to use this functionality without duplicating too much of the code in opt.cpp
No functionality change.
