Move gen in the keyword list.

Browse source 
`gen` is an edition-specific keyword used in unstable Rust, and so
belongs with `try` (as `is_unused_keyword_conditional` indicates).

Also, the cases in `is_unused_keyword_conditional` should be in
alphabetical order, to match the keyword list.

These changes don't affect the behaviour of any of the `Symbol::is_*`
functions.
