Chris Lattner
cd134c6891 * Support pointer indexing 
* Unsized arrays are a thing of the past, remove DoInsertArrayCast family
* Remove cases were we would get into infinite loops because we would insert a cast
  which would then be removed, inserting a different cast, ad infinitum...
* Remove some code that should be redundant with ExprTypeConvert code

6b2dc21b63 * Refactor trace values to work as a proper pass. Before it used to add 
methods while the pass was running which was a no no.  Now it adds the
  printf method at pass initialization
* Revamp code to use printf calls instead of the old style print_<type>
  calls.
* Simplify code

//  1. PHI nodes with multiple entries for the same predecessor.  GCC sometimes

//  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

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

     // Peephole optimize the following instructions:
     // %t1 = cast {<...>} * %StructPtr to <ty> *
     //

     //       %t1 = cast <eltype> * %t1 to <ty> *

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