fix PointerIntPair visualizer

[aaron.ballman]

Thank you for working on this, but it seems like the fix didn't go quite far enough. There are other uses of IntShift in the natvis file that are causing problems, like the ones from the PointerUnion visualizers a few lines below what was updated. I don't suppose you'd be interested in getting the rest of the uses of IntShift cleaned up as well?

Simply didn't look for other uses of IntShift :)
I'm currently not working on llvm but I still have a bunch of half-decent visualizers for llvm::Value types and the like.
