[PATCH] D68185: [Diagnostics] Warn when class implements a copy constructor/copy assignment operator, but missing the copy assignment operator/copy constructor

[David Blaikie via Phabricator via cfe-commits]

Yeah, I'm OK with warning on the deprecated cases (especially for symmetry with GCC's warning) - not sure why that didn't occur to me/why I didn't mention it in my previous comment...

Deprecation wording is, in C++17, 15.8.1 [class.copy.ctor] p6, and 15.8.2 [class.copy.assign] p2.
