When a type is renamed, we leave behind a "compatibility typealias" whose underlying type uses the new name. For generic types, though, we were using the generic parameters and environment of the original type, which is completely bogus. "Fix" this by just dropping the generic part entirely and making a typealias that refers to the /unbound/ generic type, as if written as `typealias OldName = NewName` instead of `typealias OldName<Element> = NewName<Element>`. The rest of the compiler can handle that fine.
