[improper_ctypes] Overhaul primary label - Always name the non-FFI-safe - Explain why the type is not FFI-safe - Stop vaguely gesturing at structs/enums/unions if the non-FFI-safe types occured in a field. The last part is arguably a regression, but it's minor now that the non-FFI-safe type is actually named. Removing it avoids some code duplication. 2018-02-11 18:08:48 -06:00			`static FOREIGN2: W; //~ ERROR union has unspecified layout`
