    Remove accidental hack in ipa_polymorphic_call_context::set_by_invariant
    
    I managed to commit a hack setting offset to 0 in
    ipa_polymorphic_call_context::set_by_invariant.  This makes it to give up on multiple
    inheritance, but most likely won't give bad code since the ohter base will be of
    different type.
    
    gcc/ChangeLog:
    
            * ipa-polymorphic-call.cc (ipa_polymorphic_call_context::set_by_invariant): Remove
            accidental hack reseting offset.
