Clone the full Type hierarchy into the TypeLoc hierarchy. Normalize

TypeLoc class names to be $(Type classname)Loc.  Rewrite the visitor.
Provide skeleton implementations for all the new TypeLocs.

Handle all cases in PCH.  Handle a few more cases when inserting
location information in SemaType.

It should be extremely straightforward to add new location information
to existing TypeLoc objects now.
