[PATCH] D122249: [Clang] Add a compatibiliy warning for non-literals in constexpr.

[Corentin Jabot via Phabricator via cfe-commits]

cor3ntin added a comment.

After talks with Aaron, I'm using CheckLiteralType
in all cases, which adds notes about why a type
is not literal.

We still need to branch on CPlusPlus2b because the
diagnostics take a variable number of arguments,
and I'd rather not have more diagnostics.
