[PATCH] D136919: [X86][RFC] Change mangle name of __bf16 from u6__bf16 to DF16b

[Simon Pilgrim via Phabricator via cfe-commits]

RKSimon added a comment.

What are the rules on this? Do we just handle this as an ABI breaking change and document it in the release notes - or do we need to provide any auto-upgrade path (with a warning?)?
