History
Nick Lewycky 3a73e343d0 Teach instruction simplify to use constant ranges to solve problems of the form 
"icmp pred %X, CI" and a number of examples where "%X = binop %Y, CI2".

Some of these cases (div and rem) used to make it through opt -O2, but the
others are probably now making code elsewhere redundant (probably instcombine).
