[Bug tree-optimization/26944] [4.1/4.2 Regression] -ftree-ch generates worse code

WRT this code generated by tree-ch:
  D.1305_41 = Int_Loc_3 + 1;
  if (Int_Loc_3 <= D.1305_41) goto <L0>; else goto <L2>;

AFAICT there's exactly one value for which the comparison can be false, IMO it
would be better to test directly that value instead of generating a new SSA
name and another expression.
