25d17a5001 * Factored RemovePredecessorFromBlock into BasicBlock::removePredecessor 
* Avoid messing around with this case:

%A:  br label %A
* Enable optimizations that are correct now.

1020b3982c 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.

4dd88f6fbf 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.
