Rename token types for keywords to add KW_... prefix

Some of the token types represent simple keywords; some of them do not.
It's easier to read and work out what's going on if all the simple
keyword ones have a common prefix; `KW_...` in this case.

Additionally I've renamed the four `sub`-related keywords to have a bit
more structure to them.

Also added comments.
