Hi, welcome!  Thank you for the careful and well-motivated first commit.  (I also see https://github.com/ccache/ccache/issues/772, hooray for noticing that...)

I am also not 100% sure how to write a test, but I think you may be able to observe the effect of your driver changes by running `clang -###`.  I'd expect you'd then see `-x cuda` in the output?

Same for the `.cuhi` change; I presume that with `-###` you'll be able to see that the driver is building a PCH with output name `.cuhi` even if that would crash if it actually went through.
