The name is not clear, since parameters also occupy stack slots. How about
kFirstLocalSlotIndex?

In fact, you could also introduce a kLastParamSlotIndex (=1) and use it along
kFirstLocalSlotIndex in the offset calculations.

Changed name as discussed offline.

The naming for +1 will be done in another CL.
