Make -Q --help print param defaults and min/max values

Make -Q --help print the --param default, min, max values, similar
to how it does print the defaults for other flags. This is useful
to let a option auto tuner automatically query all needed information
abourt gcc params (previously it needed to access the .def file in
the source)
