    [dict-proto] TF support for constants in dictionary mode protos, pt. 4 · c9b4f3c4
    Frank Emrich authored
    This CL is part of a  series that implements Turbofan support for
    property accesses satisfying the following conditions:
    1. The holder is a dictionary mode object.
    2. The holder is a prototype.
    3. The access is a load.
    
    This feature will only be enabled if the build flag
    v8_dict_property_const_tracking is set.
    
    This particular CL modifies existing mjsunit tests whose assumptions
    don't hold if v8_dict_property_const_tracking is enabled. This is
    done by adding special handling for the case that
    %IsDictPropertyConstTrackingEnabled() holds.
