This might be a candidate for Node itself... But that's for a separate PR/issue (Node API)

Describe the PR
Update UnnecessaryReturn. The rule is more general than before, so I guess there will be fps to find out. But it will also be much more useful. Namely it now checks return statements in initializers, constructors, and lambdas properly. Also it doesn't flag just a return statement at the very end of a method, which is exceedingly rare and useless, but recurses to find out whether we're at the end of the control flow graph of the method. So it should handle arbitrarily complex code.
