    - Renames StackParameterCount to ParameterSlotCount, to avoid
      confusion between slots and parameters, which are not in general
      equivalent.
    - Similarly, renames StackReturnCount to ReturnSlotCount.
    - Adjusts the result of GetFirstUnusedStackSlot to return one more
      than the last slot of the argument area, not including padding.
    - Renames GetFirstUnusedStackSlot to GetOffsetToFirstUnusedStackSlot
      to reflect that the result is an offset from callee to caller
      frames.
    - GetReturnsOffset is a little clearer, with adjustment for the
      different semantics of GetFirstUnusedStackSlot.
    - Renames 'optional_padding_slot' and 'first_unused_stack_slot'
      variables in Tailcall codegen to reflect that these are offsets.
