[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

> This patch fixes this by adding a new #define, "USING_FRAME_INFO_REGISTRY", which is set by the top-level define "USE_FRAME_INFO_REGISTRY". The indirection allows combining the first test with the backward compatibility check below.

I can't find `USING_FRAME_INFO_REGISTRY`.
