    Limit ranger query in ipa-prop.cc to integrals.
    
    ipa-* still works on legacy value_range's which only support
    integrals.  This patch limits the query to integrals, as to not get a
    floating point range that can't exist in an irange.
    
    gcc/ChangeLog:
    
            * ipa-prop.cc (ipa_compute_jump_functions_for_edge): Limit ranger
            query to integrals.
