To follow the style guide, and potentially improve performance, we
switch to {int} for all stack offsets. The size of the stack cannot grow
anywhere near {kMaxInt} anyway, and we have limits in place (for number
of locals, number of parameters, and function body size) which also
prevent this number from ever growing near that limit.
