Hmm we don't use the`warnings` module much since mypy is usually used on the command line. This seems a bit inconsistent with existing behavior, so maybe this should reverted. What do you think?

I've removed all calls to this method from the mypy codebase itself. So we could even think about just removing it completely. My intention with the DeprecationWarning was to help plugin developers which might be using it. Then again, I don't know if any plugins actually use it.
