Without trailing return type support, this produces unhelpful diagnostics:

$ echo -e 'auto a();' | clang++ -xobjective-c -
<stdin>:1:1: error: 'auto' return without trailing return type
auto a();
^
1 error generated.
$ echo -e 'auto a() -> void;' | clang++ -xobjective-c -
<stdin>:1:10: error: expected function body after function declarator
auto a() -> void;
         ^
1 error generated.

It should be straightforward to teach GetTypeForDeclarator that
objective-c (or perhaps anything that's not C++) is a special case, if you
don't want trailing return types there too.
