llvm::OStream provides all std::ostream functionality (by holding a
std::ostream* internally), but
* doesn't include <iostream>, avoiding per-file overhead.
* allows the stream pointer to be null, and the (inlined) operators do nothing
when that's the case. (This also allows removal of the ofstream("/dev/null")
hack Logger used when disabled, which presumably wasn't very portable)
