Code using indirect calls is broken without this, and there isn't really much value in supporting the old attempt to vary the argument placement based on uses. This resulted in more argument shuffling code anyway. Also have the option stop implying all inputs need to be passed. This will no rely on the amdgpu-no-* attributes to avoid passing unnecessary values.
