[PATCH] D33125: Introduce isoneof<T0, T1, ...> as an extension of isa<T>

[Sanjoy Das via Phabricator via llvm-commits]

Overall, I think this is a really good abstraction, but given the scope of the change I'll wait for other stakeholders to chime in.

Right now it looks like `isoneof<C>` won't do the right thing -- we should definitely have it "gracefully degrade" to `isa`.

I won't vote for making `isa` variadic since that would read weird.  `isoneof`, OTOH, is very understandable so my suggestion would be to stick with that.
