Code Review
This pull request removes a confusing error message for the deprecated -O.xx command-line flag by removing its special handling. This allows the standard argument parser to handle invalid values, which is a cleaner approach. The corresponding test is also removed. The changes are correct and improve the user experience by providing less confusing error messages. I have no further comments.

This error is confusing because -O.xx is too similar to -On which might confuse people. e.g. if a user does -O.2 thinking they're setting optimisation level but then they see an error suggesting they do -cc.2 which also won't work.
