Is there any testing that could be added to demonstrate that this semantic change is correct/avoid the regression/test the codepath that is missing coverage?

This might not be the right place to ask, but I accidentally found that no one outside `lib/Target` is actually using `emitCalleeSavedFrameMoves` with 4 arguments (please correct me if I'm wrong. I only found one call site of `emitCalleeSavedFrameMoves` with 2 arguments). Combing with the diff presented here, this patch is actually a NFC one. So I don't think adding a test will be necessary here.
A spin-off question might be: Why was `emitCalleeSavedFrameMoves` with 4 arguments got exposed as virtual function at the first place if no one is using it?
