    [runtime] Collect IC feedback in DefineDataPropertyInLiteral. · 81736c71
    franzih authored
    Add a feedback vector slot for computed property names in object
    and class literals. Introduce new slot kind for storing
    computed property names.
    
    Change StaDataPropertyInLiteral to use the accumulator (again), so
    we don't exceed Bytecodes::kMaxOperands.
    
    We assume that most computed property names are
    symbols. Therefore we should see performance
    improvements, even if we deal with monomorphic ICs only.
    
    This CL only collects feedback but does not use
    it in Reduce() yet.
