* Beginning SplitKit - utility classes for live range splitting.Jakob Stoklund Olesen2010-07-201-0/+148
This is a work in progress. So far we have some basic loop analysis to help determine where it is useful to split a live range around a loop. The actual loop splitting code from Splitter.cpp is also going to move in here. llvm-svn: 108842
