Restore the old Swift 3 behavior for source compatibility reasons: - Unqualified lookup finds static properties (but not static methods) first, then global members. - Qualified lookup into 'self' is still supported. There's no change in Swift 4 mode, where the newer more correct behavior is enabled. Fixes <rdar://problem/32570766>.
