little classes.

Add extra forwarding accessor methods so that getMethodList(), getBasicBlocks()
and getInstList() are obsolete... except for when modifying those lists.  This
makes code much more succinct and to the point.

LoopDepth.cpp: new file that calculates the depth of a loop, using
IntervalPartitions.

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.
