  Log Message:
  -----------
  [clang][dataflow] Add convenience function for analysing and `FunctionDecl` and diagnosing it.

The convenience function captures running the analysis and then collecting
diagnostics based on a `Diagnoser` object. This pattern is valuable to
clang-tidy checks which analyze a function at a time, though it could be more
generally useful for analysis clients.

  Log Message:
  -----------
  [clang-tidy] Update unchecked-optiona-access-check to use convenience function for diagnosing `FunctionDecl`s.

Also changes code in the underlying model to fit the type expected by the convenience function.
