This version of -Wimplicit-fallthrough incorporates changes I made to
address Jakub's and David's comments.
I fixed up the fixit hints handling (the output looks much better now) and
added tests for that. I also added tests for ObjC and Obj-C++ and the
warning now works for these languages too.
Accompanying changes to the core patch.
