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
instead of the pointer to load from.

* Make cast-of-self-ty DCE the dead cast instruction immediately instead of
waiting for it to be DCE'd by another sweep over the function. This speeds

* Rename MethodPass class to FunctionPass
...
- Rename runOnMethod to runOnFunction
* Transform getAnalysisUsageInfo into getAnalysisUsage
- Method is now const
- It now takes one AnalysisUsage object to fill in instead of 3 vectors
to fill in
- Pass's now specify which other passes they _preserve_ not which ones
they modify (be conservative!)
- A pass can specify that it preserves all analyses (because it never
modifies the underlying program)

// Peephole optimize the following instructions:

// %t1 = cast <eltype> * %t1 to <ty> *
This peephole eliminated 9 evil casts in the health benchmark, and
completely turned the addList method around. :)
