Much better comment preservation (#22141) * Retain comments on (and produce sourcemaps on) the equals token in initializers * Improved comments/sourcemaps for await, yield, while, and for * Retain comments on block curly-braces * Emit comments for if statements * Improved switch case comment emit * Improve comment and sourcemap emit for try/catch, throw, and continue statements * Improve sourcemap emit and comments for with statements * More accurate sourcemaps+comments emit for new, typeof, void, and delete * Improve comment emit for element access expressions * Preserve more comments on imports and exports * Make function a bit more defensive like other usages of emitTrailingCommentsOfPosition * Support preserving comments within empty lists * Handle leading comments of tokens, conditionally indent leading comments * Stop heuristically sourcemapping tokens When the transform was trivial it worked, but was unneeded, but when it was complex, it was brittle - best leave source mapping up to the transformers * Fix unneeded +1 * Tighten up element access comments * Handle comments on parenthesized expression tokens * Fix nit 2018-03-03 02:23:59 +01:00			`/1/(/2/ "foo" /3/)/4/`
