[PATCH] D102820: [Clang] Check for returns_nonnull when deciding to add allocation null checks

[Di Mo via Phabricator via cfe-commits]

modimo added a comment.

@rsmith @lebedev.ri thoughts on adding this directly to FE generation? As mentioned this isn't strictly needed and the BE can elide the check but we can also not emit it to save on AST/IR processing cost.
