UseProvidedBody should accept any body #93
Description
Look at the newly added DelegateBodyTests tests. They are failing, your job is to write generators code to make them pass. Feel free to edit them a tiny little bit (like formatting) if there is a mistake in the tests.
The UseProvidedBody accepts a delegate. This delegate code, no matter the complexity (could be simple return, could be hundreds of lines) should end up as a body for the target method. The code in this delegate should be more-or-less copied exactly as is to the target method body.
