[PATCH] D44865: [libc++] Implement P0608R1 - A sane variant converting constructor

[Eric Fiselier via Phabricator via cfe-commits]

EricWF added a comment.

This LGTM.

However, we should add tests for `const bool` and `volatile bool` before committing.

Also I would like @mclow.lists input about applying this DR early since LWG
hasn't commented on it yet.
