[PATCH] D27835: Add support to llvm::Twine for storing formatv objects

Given a function `foo(const Twine &T)`, it would be nice to be able to write `foo(formatv("{0}{1}", x, y));`.  This patch enables that.

For some reason there's some formatting-only changes in here.  I suspect this is due to an incompatibility between mono-repo and the `git clang-format` extension script.  I'll try to clean these up before submitting.
