I suspect that this one will crash in case of anonymous fields. That said, I
also don't think it's even possible to put an attribute on an anonymous field,
so we're probably fine.
However, with diagnostics specifically, the tradition isn't to put `name` into
the `Diag()` stream; the tradition is to put the decl itself, directly, by
pointer into the Diag() stream!
I.e.
```c++
const Decl *D = ME->getMemberDecl();
...
S.Diag(Loc, diag::warn_unsafe_buffer_operation) << MsgParam << D << Range;
```
This way not only it reacts to anonymous objects correctly (I think), but also
it automatically puts quotes around the name, which is something we currently
forget to do :)
