Add new cleanup pass:
...
// 1. PHI nodes with multiple entries for the same predecessor. GCC sometimes
// generates code that looks like this:
//
// bb7: br bool %cond1004, label %bb8, label %bb8
// bb8: %reg119 = phi uint [ 0, %bb7 ], [ 1, %bb7 ]
//
// which is completely illegal LLVM code. To compensate for this, we insert
// an extra basic block, and convert the code to look like this:
//
// bb7: br bool %cond1004, label %bbX, label %bb8
// bbX: br label bb8
// bb8: %reg119 = phi uint [ 0, %bbX ], [ 1, %bb7 ]
//

* 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;
}

This resolves definitions like this:

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

Operands are maintained as a vector<Use> in the User class, and operator

a virtual function call.
