Eli,

Thanks for catching this, in fact I meant to but then it slipped my mind.

The problem is actually after memset has been lowered so I filed a new bug
on it: http://llvm.org/PR2619

It might be worth filing a bug on this.  I don't think it It should be
very difficult to make GVN smart enough to deal with this.
