[PATCH] D55646: [ASTImporter] Make ODR diagnostics warning by default

[Gabor Marton via Phabricator via cfe-commits]

martong added a comment.

Just a quick note. We are pretty sure that `StructuralEquivalency` can have false positive results, i.e. it can report two decls as nonequivalent falsely. My understanding is that we should report an error only if we are absolutely certain that an error has happened, this is not the case with `StructuralEquivalency`. Consequently this should be a warning in Sema (modules) too.
