Richard Barton b068d19a15 [flang] Add details to --help screen on default behaviour
Add a usage string and a defaults section that clarifies:
 * If no input files are given, f18 reads from stdin
 * If no input files are given, f18 dumps the parse tree.
 * The default behaviour is to exec F18_FC.
 * The fefault F18_FC setting is 'gfortran'

Adds a simple regression test which tests the top and tail of the help
screen and the exit status.
