I believe this is not blocked on emscripten-core#11984 as it doesn't require Closure to emit runtime helpers.

This is mostly automated with ast-grep, bunch of custom rules, and a few manual fixups.

Care was taken to ensure that false-y conditions still use `||` where it might matter and only null-ish conditions use `??`.
