[PATCH] D73852: [clang] detect switch fallthrough marked by a comment (PR43465)

[Richard Smith - zygoloid via Phabricator via cfe-commits]

rsmith added a comment.

I'm also pretty concerned about using comments to drive warning behavior. We discussed this when first adding our gallery fallthrough warning and its suppression mechanism and made an explicit decision that we did not want comments to affect our behaviour. I don't think anything has changed in that regard.

We shouldn't enable the warning under -Wextra in language modes where there's no standard way to suppress it.
