- I->use_empty() can never be true because of the IHolder's
* Fix bug: test/Regression/Transforms/LevelRaise/2002-07-16-SourceAndDestCrash.ll
- Add a new NewCasts member to VMC to keep track of casts that have been
created and to ensure there is always a reference to the cast.
- Extend ValueHandle a bit so it can be used in an STL container
- Make sure we destroy the ValueMapCache before verifying the function
in LevelRaise.cpp

* Make ValueHandle's remove instruction from maps when they are deleted so that
no false map hits occur if a subsequent instruction is allocated to the same
space in memory. This was a VERY VERY VERY EVIL NASTY BUG to track down. :-P
