each instruction produces as "operand" -1, and the other operands as 0
.. n, as before. PhyRegAlloc::saveState() is refactored into
PhyRegAlloc::saveStateForValue().

pool allocator no end of trouble, and doesn't make a lot of sense anyway.  This
does not solve the problem with mutually recursive functions, but they are much less common.

callgraph MUCH simpler for eh using program.

still causes a crash. But it's better than before.

destination, if returning from an invoke.

Implement 'unwind' instruction.

for the Sparc backend: breaking up constant expressions. Thus, we cannot have it
guarded by a conditional, it should never be disabled.

Also, it's now available for the JIT since it is a FunctionPass.

Use visitCallSite to implement both CallInsts and InvokeInsts.

MachineConstantPool. This involved refactoring the two classes involved in
printing out Sparc assembly. In fact, they should share all this code anyway.

  it will be converted to a MachineConstantPool index during instruction
  selection
* This is now eligible to become a FunctionPass since it does not have any side
  effects outside of the function it is processing.

* Do not create new globals for constants!

Also, order #includes as per coding style guide

Make external function calls slightly less special; now they get a stack frame.
