Chris Lattner 823eb1ca11 Fix an obscure bug in PointerUnion that would bite PointerUnion3/4. Basically, 
when checking isNull(), we'd pick off the sentinel bit for the outer 
PointerUnion, but would not recursively convert the inner pointerunion to bool,
so if *its* sentinel bit is set, isNull() would incorrectly return false.

No testcase, because someone hit this when they were trying to refactor code
to use PointerUnion3, but they since found a better solution.
