48fe63526e Fix the Win32 VS2008 build:
- Make type declarations match the struct/class keyword of the definition.
 - Move AddSignalHandler into the namespace where it belongs.
 - Correctly call functions from template base.
 - Some other small changes.
With this patch, LLVM and Clang should build properly and with far less noise under VS2008.

ae5a20a917 Rearrange operands of the BranchInst, to be able to
access each with a fixed negative index from op_end().

This has two important implications:
- getUser() will work faster, because there are less iterations
  for the waymarking algorithm to perform. This is important
  when running various analyses that want to determine callers
  of basic blocks.
- getSuccessor() now runs faster, because the indirection via OperandList
  is not necessary: Uses corresponding to the successors are at fixed
  offset to "this".

The price we pay is the slightly more complicated logic in the operator
User::delete, as it has to pick up the information whether it has to free
the memory of an original unconditional BranchInst or a BranchInst that
was originally conditional, but has been shortened to unconditional.
I was not able to come up with a nicer solution to this problem. (And
rest assured, I tried *a lot*).

Similar reorderings will follow for InvokeInst and CallInst. After that
some optimizations to pred_iterator and CallSite will fall out naturally.

f718e70c7e Instead of storing operands as std::vector<Use>, just maintain a pointer
and num operands in the User class.  this allows us to embed the operands
directly in the subclasses if possible.  For example, for binary operators
we store the two operands in the derived class.

The has several effects:
  1. it improves locality because the operands and instruction are together
  2. it makes accesses to operands faster (one less load) if you access them
     through the derived class pointer.  For example this:

Value *GetBinaryOperatorOp(BinaryOperator *I, int i) {
  return I->getOperand(i);
}

Was compiled to:

_Z19GetBinaryOperatorOpPN4llvm14BinaryOperatorEi:
        movl    4(%esp), %edx
        movl    8(%esp), %eax
        sall    $4, %eax
        movl    24(%edx), %ecx
        addl    %ecx, %eax
        movl    (%eax), %eax
        ret

and is now compiled to:

_Z19GetBinaryOperatorOpPN4llvm14BinaryOperatorEi:
        movl    8(%esp), %eax
        movl    4(%esp), %edx
        sall    $4, %eax
        addl    %edx, %eax
        movl    44(%eax), %eax
        ret

Accesses through "Instruction*" are unmodified.

   3. This reduces memory consumption (by about 3%) by eliminating 1 word of
      vector overhead and a malloc header on a seperate object.
   4. This speeds up gccas about 10% (both debug and release builds) on
      large things (such as 176.gcc).  For example, it takes a debug build
      from 172.9 -> 155.6s and a release gccas from 67.7 -> 61.8s
