Add a common parent `ConstantData` to the constants that have no operands. These are guaranteed to represent abstract data that is in no way tied to a specific Module. This is a good cleanup on its own. It also makes it simpler to disallow RAUW (and factor away use-lists) on these constants in the future. (I have some experimental patches that make RAUW illegal on ConstantData, and they seem to catch a bunch of bugs...) llvm-svn: 261464
