pass the size and alignment of each field. Take advantage of this to pass a constant size and alignment when possible. This avoids the need to recursively find type metadata for every field type, allowing generic recursively-structured classes to be built. There are a number of more complicated cases that this approach isn't good enough for, but this is good enough for now to fix rdar://18067671. Also make an effort to properly support generic subclasses of Objective-C classes. Swift SVN r21506
