Cleaned up and brought up to date the help text...

Cleaned up and brought up to date the help text for -X and -Y options.
Made some enhancements to PhasesSetting, which are documented if you
run scalac -X or -Y. (Try it!) Disabled some dead settings and renamed
others to reflect their current purpose. No review.
