Add feature flag for the index unit path warning removal
[Frontend] Add feature flag for the index unit path warning removal

6e683ca823cc987544faa7a2696d3c5e70901432 removed the warning that was
being output when `-index-unit-output-path` was given without
`-index-store-path`. Add a feature flag to mark the compiler as having
removed this warning.
