Adds a class `raw_ostream_iterator` that behaves like
std::ostream_iterator, but can be used with raw_ostream.
This is useful for using raw_ostream with std algorithms.

For example, it can be used to output std containers as follows:

std::vector<double> V = { 0.1, 0.2, 0.3 };
std::copy(V.begin(), V.end(), raw_ostream_iterator<double>(outs(), ", "));
// Output: "0.1, 0.2, 0.3, "

The API tries to follow std::ostream_iterator as closely as is
practically possible.
