Summary

When writing driver tests, it's useful to have a way to output arguments
verbatim (i.e. without any quoting and escaping). For example, on
Windows today, the installation directory is output without backslashes
being escaped, but any -internal-isystem arguments passed by the driver
to the frontend will have backslashes escaped in the -### output, making
it impossible to write a FileCheck match against the installation
directory. Add a new argument to avoid any quoting and escaping to ease
driver testing. Make this argument output to stdout instead of stderr to
avoid needing 2>&1 in all the driver tests.

I'm not tied to the name -###-verbatim and am open to suggestions if anyone can think of something better.

My troll suggestion was -####, but @compnerd didn't like that for some reason...
