Description

Simplify each loop in a loop nest recursively. This takes a potentially un-simplified loop L (and its children) and turns it into a simplified loop nest with preheaders and single backedges. It will update \c DominatorTree, \c LoopInfo, \c ScalarEvolution and \c MemorySSA analyses if they're non-null, and LCSSA if \c PreserveLCSSA is true.
