[ASTImporter] Call to HandleNameConflict in VisitRecordDecl mistakeningly using Name instead of SearchName
https://reviews.llvm.org/D51633 added error handling to the ASTNodeImporter::VisitRecordDecl for the conflicting names case. This could lead to erroneous return of an error in that case since we should have been using SearchName. Name may be empty in the case where we find the name via D->getTypedefNameForAnonDecl()->getDeclName().
This fix is very similar to https://reviews.llvm.org/D59665
