Cameron Zwarich b703654edc Remove code for updating dominance frontiers and some outdated references to 
dominance and post-dominance frontiers.

llvm-svn: 123725
 2011-01-18 04:11:31 +00:00
Chris Lattner bf0aa927cc split dom frontier handling stuff out to its own DominanceFrontier header, 
so that Dominators.h is *just* domtree.  Also prune #includes a bit.

Dan Gohman 28943873e6 Use do+while instead of while for loops which obviously have a 
non-zero trip count. Use SmallVector's pop_back_val().

Dan Gohman 9a6fef0a52 Simplify code by using SmallVector's pop_back_val() instead of 
separate back() and pop_back() calls.
