Fix warn_report and error_report macros.

Originally they didn't check err.kind(), since err.kind() can never
increase their severity.  We lost that behavior with !1386, and we
became dependent on it with arti!1383.  Since they both merged at
the same time, CI broke.

This patch restores their original behavior.
