[PATCH] D11490: [Concepts] Add diagnostic: non template declaration

[Hubert Tong]

hubert.reinterpretcast added a comment.

In `test/Parser/cxx-concept-declaration.cpp`:

  concept D1 = true; // expected-error {{C++ requires a type specifier for all declarations}}

triggers the new error and fails the test.
