This patch changes the DWARF representation of bound generic struct to a nested struct where the (sized) outer struct is anonymous and thus distinct and the inner struct in uniqued and sizeless. This is anologous the the previous commit that did the same thing for bound generic enums. rdar://problem/56521648
