f57b845547 * 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

//  bb7: br bool %cond1004, label %bbX, label %bb8
//  bbX: br label bb8
//  bb8: %reg119 = phi uint [ 0, %bbX ], [ 1, %bb7 ]

b20807f23e * Export method to merge identically named methods
* Add code to fix PHI nodes that are missing arguments.  These PHI nodes can
  be generated by GCC if there is an uninitialized variable flowing into a merge
  point.  For example:

int foo(int y) {
  int X;
  if (y) X = 1;
  return X;
}

b6b26921e3 Add code to link method together with the same name if one is vararg and the other isn't.
This resolves definitions like this:
   %list * "foo"(...)
   %list * "foo"(int)

together which can often occur because C programmers don't put prototypes in like they should.  GRR

* Changed getOpcodeName to return a const char * instead of string
* Added a getOpcode method to replace getInstType
* Changed code to use getOpcode instead of getInstType

c8b25d40cb Changed the fundemental architecture of Operands for Instructions. Now
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!
