Volodymyr Sapsai 5f8b9092ff [ODRHash] Fix null pointer dereference for ObjC selectors with empty slots. 
`Selector::getIdentifierInfoForSlot` returns NULL if a slot has no
corresponding identifier. Add a boolean to the hash and a NULL check.

Richard Trieu a986a31242 Ensure canonical type is actually canonical. 
ASTContext::applyObjCProtocolQualifiers will return a canonical type when given
a canonical type and an array of canonical protocols.  If the protocols are not
canonical then the returned type is also not canonical.  Since a canonical type is needed, canonicalize the returned type before using it.  This later prevents
a type from having a non-canonical canonical type.
