e005dc792d * Factored RemovePredecessorFromBlock into BasicBlock::removePredecessor
* Avoid messing around with this case:
  br label %A
%A:  br label %A
* Enable optimizations that are correct now.

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.

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.
