cc746868d7 Use node->getOpCode() instead of node->getMachineInstr()->getOpCode(). 
Much nicer.

7969ed3025 * 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

841ffd6a44 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.

347a3cab9e Added support for bitwise logical operators. Use different labels for 
for these than for boolean logicals to avoid making Burg diverge.

ef146ce336 Fixed function getEscapedString to follow the Sparc assembly rules 
for symbol names!  (And renamed it to getValidSymbolName).

a7383895cd Fix bugs in FITOS/D instruction generation. 
The space for optional args in the stack frame is now being computed,
so finish the code generation for the variable `alloca'.
Finally, made a major overhaul of how stack frame is managed.

caf89d678c * 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
