[PATCH] D41228: [ObjC] Enable __strong pointers in structs under ARC

[Akira Hatanaka via Phabricator via cfe-commits]

- Improved IRGen for copying trivial fields in a non-trivial C struct. IRGen in CGNonTrivialStruct.cpp now calls a single memcpy if there are consecutive trivial fields in a struct (it does something similar to what FieldMemcpyizer does)

- IRGen for structs containing bitfields was not correct, so I fixed that too.
