Most of the time the routines optimized down to the last tick are incredibly ugly.

It would need a flag and testing that flag (another conditional jump). A very rough estimate: the saving comes less than once in 100, saves around 50 cycles; while the cost is 4 cycles per each call, 400 cycles overall. Not worth.
