Doug Gregor 3d15bf3d55 Introduce a diagnostic-formatting engine and port most of the parser's ...

diagnostics over to it.

There are a few differences between this diagnostic engine and Clang's
engine:
  - Diagnostics are specified by a .def file (Diagnostics.def), rather
  than via tblgen, which drastically simplifies the build and makes
  code completion work when you add a new diagnostic.
  - Calls to the "diagnose()" method are safely typed based on the
  argument types specified in the .def file, so it's harder to write a
  diagnostic whose expected arguments (in the string) and whose actual
  arguments (in the code) don't match.
  - It uses variadic templates, so it hangs with the cool kids.
