ghc: allow --show-options and --interactive together
Summary:
Previously 'ghc --show-options' showed all options that GHC can possibly
accept. With this patch, it'll only show the options that have effect in
non-interactive modes.
This change also adds support for using 'ghc --interactive --show-options'
which previously was disallowed. This command will show all options that have
effect in the interactive mode.
The CmdLineParser is updated to know about the GHC modes, and then each flag
is annotated with which mode it has effect.
This fixes #9259.
Test Plan:
Try out --show-options with --interactive on the command line. With and without
--interactive should give different results.
Run the test suite, mode001 has been updated to verify this new flag
combination.
