Add back `UnparsedStmt`

If the user doesn't use any `import` declarations, there is no reason to parse their code at all, so having the option of falling back to `UnparsedStmt` can potentially save us some headaches down the road.

The new rule now is that if you have the "no checking" flag on, *and* the parser hasn't yet seen any `import` declarations, then it still used `UnparsedStmt` to avoid touching function bodies.
Otherwise, I go ahead and parse function bodies, and assume I can rewrite any code I can semantically understand.
