d4d1cb558c Put in test of SCCP. Watch out though, because we need to sort the 
constant pool for the final check to work.  :(

b2d6da7f1e 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.

c75d18eb19 IntervalPartition: recode to use IntervalIterator to do all the work

IntervalPartitions.

108acdb1a7 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.
