The original motivation for this PR was to prevent throwing in #12436, but then I realized that this is an error that it's really easy to recover from.

  1. Half of the fixtures output modified in this PR where throwing and now they don't.
  2. The other half where throwing Unexpected token, expected \";\" and now they throw a similarly unuseful error (adding ; was not the necessary fix in these fixtures).

Can you rebase on #12375 ? So we are confident that it also works when estree is plugged in.
