SIL: Add support for capturing the dynamic Self metatype If a closure captures the dynamic 'Self' type, but no value of type 'Self' (for example, it is possible to have a weak capture of 'self'; if the weak reference becomes nil, there's no way for the closure to get the dynamic 'Self' type from the value). In this case, add a hidden argument of type $Self.Type, and pass in the Self metatype. Fixes <https://bugs.swift.org/browse/SR-1558> / <rdar://problem/22299905>.
