SI-8736 Restore -language to former glory
MultiChoice allows -language to work like -Xlint.
The bug as described was that the setting value was set instead of updated
(++=) with additional flags.
The unreported bug was that `_` no longer set all settings.
The corrected behavior is that "contains" means "it was enabled, or
_ was set and it was not disabled explicitly."
That is the behavior of `-Xlint` but with a different mechanism,
since each lint option is a Setting.
A semantic difference is that -Xlint enables all the lint options,
but -language does not enable all the language features. `scalac -X` does
not explain this additional behavior of the `-Xlint` flag.
Also worth noting that `scalac -feature -language unused.scala` failed
in 2.11.1 but succeeds silently now.
