2b7bb7a986 - Add new methods to LoopInfo: getLoopPreheader, addBasicBlockToLoop. 
These allow extra information to be easily gathered, and loopinfo to be
    updated.

e4314ed315 Fix: ConstantMerge/2002-09-23-CPR-Update.ll 
Basically, this bug boiled down to calling replaceUsesOfWith on a constant,
which changed it's shape in an illegal way.  This pass now goes through all
of the trouble neccesary to do the replacement on constants.
