[ASTImporter] Make ODR error handling configurable

Authored by gamesh411 on Mar 4 2019, 5:34 AM.



ODR errors are not necessarily true errors during the import of ASTs.
ASTMerge and CrossTU should use the warning equivalent of every CTU error,
while Sema should emit errors as before.

This revision is the alternative of the abandoned D55646.
Now Sema uses the old behavior of emitting ODR errors while merging and importing is done in a more lenient way.

Hi Gabor,
This patch LGTM mostly, but there is a comment inline.


I see the argument order change but I don't see any callers changed. Do we really need this order change?

  • Revert member order to original

Strictly speaking, there is no need for this change, the constructor param order does not match the initialization, but that is just a nit. I have updated the diff. Cheers :)
