[PATCH] D49129: [Support] raw_ostream << Error&& and formatv(..., Error&&) consume the Error.

[Sam McCall via Phabricator via llvm-commits]

Herald added a subscriber: llvm-commits.

This makes them behave like the current llvm::toString (in Error.h).

Because of this, we can unify the behavior of llvm::toString with
llvm::to_string, and deprecate the former.
