SILGen: Emit default witness tables for all non-@objc protocols SILGen will now be able to look up the default implementation corresponding to a requirement while emitting conformances, and reference the default witness thunk instead of emitting duplicate thunks for each conforming type. IRGen continues to only emit resilient defaults if the protocol itself is resilient; otherwise, it just ignores the default witness table.
