Chandler CarruthandChristopher Di Bella 14a213d095 Apply the unused-without-definition check to implicit parameters (#7270) ...

The `unused` modifier is rejected on parameters of a function
declaration, but the check only covered the explicit parameter list, so
an implicit parameter (such as self or a compile-time binding) could
carry unused without a definition. Check the implicit parameter list
too.

The code changes and the test updates are split into two commits for
easier review.
