This brings this control in line with other diagnostic controls we have which operate on a per-group level. 'DefaultIgnoreWarnings' diagnostic group option applies to all warnings belonging to a certain diagnostic group. The inheritance rules are: - Marking a diagnostic group as 'DefaultIgnoreWarnings' means warnings belonging to this group will not be emitted by-default - Warnings belonging to sub-groups of this group will also not be emitted by-default - Enabling a 'DefaultIgnoreWarnings' group (with '-Werror','-Wwarning', etc.) means warnings belonging to this group will be emitted. - Warnings belonging to sub-groups of this group will also be emitted. - Warnings belonging to super-groups of this group will not be affected.
