------- Comment #8 from law at redhat dot com  2006-03-21 05:10 -------
Today's patch picks up the missed const-propagation and allows 
simplification of the modulo operation.

THere's still the opportunitity to use range information to simplify
a conditional.  However, fixing that is just basically iterating
VRP in response to CFG changes -- not something we're going to
do as it's simply too expensive.

Thus I'm changing the state of this bug to WONTFIX.
