// here we have a case of indirect assignment: *t1 = expr;
// normally we would need to push t1 and that will cause spilling of t2
//
// TODO: an interesting case arises in unused x[i]++ and ++x[i] :
// we have trees that look like:
//
// t1 = &(x[0])
// t2 = *t1
// *t1 = t2 + 1
//
// t1 = &(x[0])
// t2 = *t1 + 1
// *t1 = t2
//
// in these cases, we could keep t2 on stack (dev10 does).
// we are dealing with exactly 2 locals and access them in strict order
// t1, t2, t1, t2 and we are not using t2 after that.
// We may consider detecting exactly these cases and pretend that we do not need
// to push either t1 or t2 in this case.
