Chris Lattner c3a6f546de A silly stupid test of the loop depth calculator was added. REMOVE in the
future.

Chris Lattner ed59025460 IntervalPartition: recode to use IntervalIterator to do all the work
LoopDepth.cpp: new file that calculates the depth of a loop, using
IntervalPartitions.

Chris Lattner 3fe4504c28 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

TODO: add IntervalPartition capability to split intervals between the looping
portion and the "tail" portion.
