[PATCH] D98224: [cmake] Enable -Werror=return-type

[Dave Lee via Phabricator via llvm-commits]

kastiglione added a comment.

Reverted because some versions of gcc can emit `Return-type` warnings on functions that have exhaustive switches over enums. A fix is to use `llvm_unreachable` but that's not currently done everywhere (and also seems like a poor/unnecessary practice).
