I've added that, and additionally made this optimization only active if the new -Oodeadvalues optimization switch is used (it's also part of -O4), because it can change the behaviour of code due to the removal of implicit side-effects caused by the original calculation of those parameters (range check errors, segmentation faults, ...).
