Big changes. Interval*.h is now more or less finalized. IntervalPartition

is recoded to use IntervalIterators. IntervalIterators can now maintain
their own memory or let an external entity do it.
Loop depth is a new user of IntervalPartition for calculating the loop
nesting depth of a basic block

portion and the "tail" portion.
