"alignment" of the index for this particular argument into the number of
possible storate locations. This change adjusts getSyscallArg to take its
index parameter by reference instead of value and to adjust it to point to the

current one. This way, the rules for the new argument can be applied locally

later, as opposed to scattering them throughout the function or using them in
place in long expressions. It also discourages using getSyscallArg over and
