generation, and make sure we generate thunks when the function is defined
rather than when the vtable is defined.

PointerUnion == PointerUnion does not do what I thought it did. Also, fix a thinko in a PointerUnion::get call.

 - The issue is that PCH uses a stat cache, which may reference files which have
   been deleted or moved. In such cases ContentCache::getBuffer was returning 0
   but most clients are incapable of dealing with this (i.e., they don't).

   For the time being, resolve this issue by just making up some invalid file
   contents and. Eventually we should detect that we are in an inconsistent
   situation and error out with a nice message that the PCH is out of date.

Only emit the vtable definition if the class has a key function and we're emitting it, or if the class doesn't have a key function and we are emitting the complete constructor.
