IRGen: Tail-emplace dependent vwtables into generic metadata patterns. If a generic type has dynamic layout, the value witness table for its instances is dependent on its generic parameters for size and alignment. Instead of emitting a global symbol for the vwtable in these circumstances, embed the value witness table template in the generic metadata template so that both get instantiated in tandem by the runtime when the generic instance metadata is requested.
