ConvertExpressionToType
* Make ValueHandle's remove instruction from maps when they are deleted so that
  no false map hits occur if a subsequent instruction is allocated to the same
  space in memory.  This was a VERY VERY VERY EVIL NASTY BUG to track down. :-P

2b011e7b50 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 ]

bcdf581aec * 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 X;
  if (y) X = 1;
  return X;

fb0626b9ed 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)

7682955ac0 * Add comments for peepholes
* Implement new peephole:
     // Peephole optimize the following instructions:
     // %t1 = cast {<...>} * %StructPtr to <ty> *
     //
     // Into: %t2 = getelementptr {<...>} * %StructPtr, <0, 0, 0, ...>
     //       %t1 = cast <eltype> * %t1 to <ty> *

  This peephole eliminated 9 evil casts in the health benchmark, and
  completely turned the addList method around.  :)

c00392210d Broad superficial changes:
* Renamed getOpcode to getOpcodeName
* 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

6f7587e4d3 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!
