Because diagnostics and their notes are not connected at the API level, if the error message for an overload is emitted, then the overload candidates are completed - if a diagnostic is emitted during that work, the notes related to overload candidates would be attached to the latter diagnostic, not the original error. Sort of worse, if the latter diagnostic was disabled, the notes are disabled. Reviewers: rsmith Differential Revision: https://reviews.llvm.org/D61357 llvm-svn: 359854
