Fix bug in the simplification of inexact comparisons
On 31/1/2011 Paul Guyot reported a bug in the native code compilation of inexact equality/inequality tests between floats and integers. The relevant test was: f(X) -> Y = X / 2, Y == 0. and hipe erroneously evaluated the calls f(0) and f(0.0) to 'false'. The culprit was in the simplification code of the Icode range analysis which used an erroneous test (lists:any/1 instead of lists:all/1).
