This patch changes the DWARF representation of bound generic enums to a nested struct where the (sized) outer struct is anonymous and thus distinct and the inner struct in uniqued and sizeless. BoundGenericEnums may have different sizes depending on what they are bound to, but still share a mangled name. rdar://problem/56521648
