[PATCH] D119571: [funcattrs] check reachability to improve noreturn

[Reid Kleckner via Phabricator via llvm-commits]

rnk added a comment.

Do we know which pass introduces unreachable code without cleaning it up? That seems like a missed optimization, possibly a phase ordering issue, or we could tack on a `removeUnreachableBlocks` to whichever pass is modifying the CFG in the first place.
