Please also add tests for
- the `cmp_*` functions,
- `format_arg_store`
- `*_sat` functions

since they are also affected by this change.

I think it's OK to add a `.verify.cpp` test for `format_arg_store` that makes sure we diagnose unsupported sizes for now if it's non-trivial to make it work. The other functions should probably work out of the box.
