* 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

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!
