I didn't love creating a new function for this but there wasn't another obvious place to put it

Your comment made me think about an alternative approach. validateCoverageArgs could be parseCoverageArgs that parses the args, diagnoses failures, and then returns an array of (original, remapped) pairs. Then, we render that array to arguments in addCommonFrontendOptions. What you do you think about that approach?

(I'm open to make any changes like that) Gut feeling is it might not be worth adding that much processing to these options considering we don't even handle them, it feels like it could increase the surface area for bugs around this

Sure. I'm fine with treating this as a "validate" call like you have it, but wanted to float the idea in case you preferred this alternative design. I don't feel strongly about it.

I did this manually because I couldn't get the option generation working, but I think I got the right stuff here

Looks fine. We can do a separate regeneration pass.
This is analogous to this change in Driver.cpp swiftlang/swift#32175
