[PATCH] D78000: [ASTImporter] Fix handling of not defined FromRecord in ImportContext(...)

[Shafik Yaghmour via Phabricator via cfe-commits]

shafik added a comment.

I am open to different approaches to this problem, this is opening attempt at fixing it but I may be missing other interactions.

AFAICT starting the definition of `ToRecord` the way  `CompleteDecl(…)`  does when we know `FromRecord` is not defined is just broken for the `RecordDecl` case if we have bases.

It took me a lot of time to come up with this reproducer from a real life issue debugging `llc`.
