f9c3f6178a It doesn't matter what the 2nd operand is; if the GEP has 2 operands and 
the first is a zero, we should leave it alone.

ef192b1a19 Add helper function. 
Don't touch GEPs for which DecomposeArrayRef is not going to do anything
special (e.g., < 2 indices, or 2 indices and the last one is a constant.)

7cf9f6f4b1 Updates to work with recent Statistic's changes: 
* Renamed StatisticReporter.h/cpp to Statistic.h/cpp
    * Broke constructor to take two const char * arguments instead of one, so
      that indendation can be taken care of automatically.
    * Sort the list by pass name when printing
    * Make sure to print all statistics as a group, instead of randomly when
      the statistics dtors are called.
    * Updated ProgrammersManual with new semantics.

4bcec53ed7 Extract most of the transformation into an externally accessible 
function -- DecomposeArrayRef(GetElementPtrInst* GEP) -- that can
be invoked on a single instruction at a time.

bbe47f2e7d Eliminate cast instructions: use only GEPs in decomposed sequence. 
Don't decompose if there are 2 indices with 0 as first index.
Compute Changed flag correctly in runOnBasicBlock().

536cf1b13f * 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)
* 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  The Method class is obsolete (renamed) and all references to it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.
