[PATCH] D150430: Implement BufferOverlap check for sprint/snprintf

[Arnaud Bienner via Phabricator via cfe-commits]

Thanks for the review :)

I implemented the suggested changes.

Just one question: `PointeeTy.isNull()`: is this guaranteed to always work even though `getType()->isAnyPointerType() == false`?

I'm assuming yes since the tests still pass, but wanted to confirm this is the best way to do this check for `char*` arguments.
