microsoft/TypeScript#15473 added the
unique
keyword to the language. This adds support in babylon to parse it. There were no necessary changes to the generator, which already handles any keyword, or to the plugin, which erases all types without needing to look at their contents.@rbuckton and @DanielRosenwasser for review.
See also eslint/typescript-eslint-parser#433, which does the same thing in their parser. @azz @JamesHenry
