Joe Groff f01af883fc IRGen: Use known value witness tables for common type layouts. ...

If a type has the same layout as one of the basic integer types, or has a single refcounted pointer representation, we can use prefab value witness tables from the runtime instead of instantiating new ones. This saves quite a bit of code size, particularly in the Apple SDK overlays, where there are lots of swift_newtype wrappers and option set structs.
