[wasm2js] Properly handle loops without labels (#7100)

When a loop has no name, the name does not matter, but we also cannot
emit the same name for all such loops, as that is invalid JS. Just do not
emit a while(){} at all in that case, as no continue can exist anyhow.

Fixes #7099

Also fix two missing * in error reporting logic, that was printing pointers
rather than the expression we wanted to print. I think we changed how
iostream prints things years ago, and forgot to update these.
