Rollup merge of #55632 - ollie27:deny_overflowing_literals, r=Centril

Deny the `overflowing_literals` lint for all editions

The `overflowing_literals` was made deny by default for the 2018 edition by #54507, however I'm not aware of any reason it can't be made deny by default for the 2015 edition as well.
