Joyee Cheung 1e6294d3c3 [class] initialize brand after super() in nested arrow function
Handle the case of nested super() by checking if the class scope
contains a private brand. In this case the ContextScope chain
is different from the actual context chain so this added back
the AddPrivateBrand() runtime function but with the additional
step of walking the context chain to get the correct class
context that will be stored as the value of the brand property
for the debugger.
