2521ae1011 Implement a more powerful, simpler, pass system. This pass system can figure 
out how to run a collection of passes optimially given their behaviors and
charactaristics.

Convert code to use it.

the BasicBlock class where they should be.  pred_begin/pred_end become methods on BasicBlock,

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.
