- Refactored patch to use incrementing Cost value, to be compared with Budget.

There probably isn't much I can do in this patch to take away all @lebedev.ri 's concerns regarding the comparison operators, but hopefully this patch is now written in such a way that it is clear and acceptable to everyone. I'd be happy to follow this up with possible changes to the nature of InstructionCost itself, like I suggested earlier, if that is helpful.
