some minor cleanups to ParseObjCTypeName:

1. Remove a bogus assertion, clients other than sema can return a
   null pointer from actions that result in ParseTypeName returning null.
2. Remove dead RParenLoc variable.
3. Simplify control flow handling error conditions.
4. On a major failure, we should skip until ')' not until '}'.
