[PATCH] D58797: [Sema] Add some compile time _FORTIFY_SOURCE diagnostics

[George Burgess IV via Phabricator via cfe-commits]

george.burgess.iv added a comment.

We have warnings like -Wdivision-by-zero that take reachability into account: https://godbolt.org/z/3PD-eF. I don't immediately know how it's all done (e.g. in batch because CFG construction is expensive? ...), but looking there for inspiration may be useful.
