Tighten up the AnalysisUsage of lots of passes, primarily to correctly indicate whether or not they invalidate the CFGA

  - 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)
* s/Method/Function/g in other random places as well

class.  The Method class is obsolete (renamed) and all references to it
are being converted over to Function.

out that almost always the result of the add was the same as the GEP that
would be generated.  In this case, however, it wasn't, so bad things happened.

* Unsized arrays are a thing of the past, remove DoInsertArrayCast family
* Remove cases were we would get into infinite loops because we would insert a cast
  which would then be removed, inserting a different cast, ad infinitum...
* Remove some code that should be redundant with ExprTypeConvert code

Convert backward conversion of expression trees into a new more powerful bidirectional approach.  Add transforms for more instructions.

* Implement new peephole:
     // Peephole optimize the following instructions:
     // %t1 = cast {<...>} * %StructPtr to <ty> *
     //
     // Into: %t2 = getelementptr {<...>} * %StructPtr, <0, 0, 0, ...>
     //       %t1 = cast <eltype> * %t1 to <ty> *

  This peephole eliminated 9 evil casts in the health benchmark, and
  completely turned the addList method around.  :)
