History
Jakob Stoklund Olesen 0253df9a89 After splitting, the remaining LiveInterval may be fragmented into multiple 
connected components. These components should be allocated different virtual
registers because there is no reason for them to be allocated together.

Add the ConnectedVNInfoEqClasses class to calculate the connected components,
and move values to new LiveIntervals.

Use it from SplitKit::rewrite by creating new virtual registers for the
components.
