Note that Deparse turns both while () {} and for (;;) {} into while (1) {}.

All three are identical in the optree, but it's closer to while () {}. No "1" constant exists. All C-style for loops, while loops and bare loops ("{ ... }") are implemented using the same loop op. The condition of "while (1)" is completely optimised away.
