  - 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

Operands are maintained as a vector<Use> in the User class, and operator
iterators are provided as before.  Getting an operand no longer requires
a virtual function call.

WARNING: getOperand(x) where x >= getNumOperands() will now assert instead
of returning null!

Optimizations now live in the 'opt' namespace

* Avoid messing around with this case:
  br label %A
%A:  br label %A
* Enable optimizations that are correct now.

  * Convert post to pre-increment for for loops
  * Use generic programming more
  * Use new Value::cast* instructions
  * Use new Module, Method, & BasicBlock forwarding methods
  * Use new facilities in STLExtras.h
  * Use new Instruction::isPHINode() method
