Rollup merge of #103159 - cuviper:check_pow-final-try_opt, r=Mark-Sim…

…ulacrum Remove the redundant `Some(try_opt!(..))` in `checked_pow` The final return value doesn't need to be tried at all -- we can just return the checked option directly. The optimizer can probably figure this out anyway, but there's no need to make it work here.
