glsl: Add a file argument to the IR printer.

While we want to be able to print to stdout for glsl_compiler, for
debugging drivers we want to be able to dump to stderr because that's
where other driver debug (like LIBGL_DEBUG) tends to go, and because some
apps actually close stdout to shut up their own messages (such as the X
Server, or NWN).
