Looks good as such, but can you provide more information? What kind of decisions and what new arguments?

Should the title mention TargetSubtargetInfo instead of MCSubtargetInfo?

Should it be propagated down to the base `TargetInstrInfo`? There are a lot of TII methods that need STI, but currently have to obtain it via MF / MI / MBB.
