Chris Lattner 682a7dc653 Fix a bug compiling PR1978 (perhaps not the only one though) which 
was incorrectly simplifying "x == (gep x, 1, i)" into false, even 
though i could be negative.  As it turns out, all the code to 
handle this already existed, we just need to disable the incorrect
optimization case and let the general case handle it.
