Allow deserialization of just the fields of a record, when we want to iterate over them, instead of deserializing the complete declaration context of the record. Iterating over the fields of a record is very common (e.g to determine the layout), unfortunately we needlessly deserialize every declaration that the declaration context of the record contains; this can be bad for large C++ classes that contain a lot of methods. Fix this by allow deserialization of just the fields when we want to iterate over them. Progress for rdar://7260160. llvm-svn: 116507

Store in PCH the key function of C++ class to avoid deserializing the complete declaration context in order to compute it. Progress for rdar://7260160. llvm-svn: 116508
