* Remove dead code from ExprTypeConvert.cpp
...
- 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

Fix a major source of "type unsafety", where a cast is neccesary, but can

be put either before or after a load. We chose to cast the value loaded

waiting for it to be DCE'd by another sweep over the function. This speeds
this up noticably.

* Rename MethodPass class to FunctionPass

* Transform getAnalysisUsageInfo into getAnalysisUsage
- Method is now const
- It now takes one AnalysisUsage object to fill in instead of 3 vectors
to fill in

they modify (be conservative!)
- A pass can specify that it preserves all analyses (because it never
modifies the underlying program)
