Pete Bacon Darwin 76979e12c9 refactor(compiler): remove not-null operator hack from lexer (#28978)
The parts of a token are supposed to be an array of not-null strings,
but we were using `null` for tags that had no prefix. This has been
fixed to use the empty string in such cases, which allows the `null !`
hack to be removed.
