0bf7bad0c3 * Add better caching of data to avoid silly recusions 
* Only check to see if uses of instructions can be converted for expressions... so we don't look at all of the uses of a constant.  This was making the code unnecessarily conservative

e64574ce71 Major change to how defs are found when adding dependences (they 
are now found as part of the initial walk of the machine code).
Also memory load/store instructions can be generated for non-memory
LLVM instructions, which wasn't handled before.  It is now.

ea38c0e85c * Switch to operation on pointers with PointerTy more consistently 
* Fix misspeling
* Catch SIGFPE for traps
* info XXX now prints the raw contents of the GenericValue
* Switch to calloc instead of malloc (temporarily I hope) to bandaid Olden benchmarks
* Implement binary And & Or
* Convert expressions like this:
     PointerTy SrcPtr = getOperandValue(I->getPtrOperand(), SF).PointerVal;
  to:
    GenericValue SRC = getOperandValue(I->getPtrOperand(), SF);
    PointerTy SrcPtr = SRC.PointerVal;
  because the prior way confuses purify.
* Taint the initial values of the value planes
* Handling 'print bb4' in the interpreter without crashing
* Print nicer stack frames with concise return type
* printf doesn't suck nearly as badly as it used to

5b497ee7c2 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 ]

e99c66b74f * 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.  :)
