[PATCH] D122820: [GH54588]Fix ItaniumMangler for NTTP unnamed unions w/ unnamed structs

[Erich Keane via Phabricator via cfe-commits]

erichkeane added a comment.

Handle the unnamed bitfield case.

I'm still not sure how to reproduce the 'unreachable' example I added that @rjmccall suggested was possible, nor how we can deal with that, so waiting on his feedback for how he thinks we should handle that case.

Presumably I could replace it with a 'don't know how to handle that yet' fatal error like we do in the MS Mangler?
