New Revision: 61874

URL: http://llvm.org/viewvc/llvm-project?rev=61874&view=rev
Log:

Sometimes, objective-c creates multiple tree nodes for "id". In such cases, only the main variant tree node has all the info. 

If a type node's main variant is neither used for typedef nor for qualified types then reuse main varinat type.
