4bded629ca Correct problem that allows indirect function calls

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

cb87df31db Fixed instruction information for RDCCR and WRCCR. 
Fixed selection to create a TmpInstruction for each integer CC register
(since it is an implicit side-effect, unlike FP CC registers which are
explicit operands).

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 foo(int y) {
  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)

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