Gabor Marton 2afbfb6b22 [ASTImporter] Mark erroneous nodes in shared st 
Summary:
Now we store the errors for the Decls in the "to" context too. For
that, however, we have to put these errors in a shared state (among all
the ASTImporter objects which handle the same "to" context but different
"from" contexts).

After a series of imports from different "from" TUs we have a "to" context
which may have erroneous nodes in it. (Remember, the AST is immutable so
there is no way to delete a node once we had created it and we realized
the error later.) All these erroneous nodes are marked in
ASTImporterSharedState::ImportErrors.  Clients of the ASTImporter may
use this as an input. E.g. the static analyzer engine may not try to
analyze a function if that is marked as erroneous (it can be queried via
ASTImporterSharedState::getImportDeclErrorIfAny()).
