…en using a Symbol When setting a property trap with JavascriptProxy::SetPropertyTrap using a symbol as a property id, we incorrectly assume that JavascriptProxy::GetName returns a PropertyString. The case for a JavascriptSymbol is unhandled, and we do a static cast leading to type confusion. Fix is to handle any cases other than PropertyString by using nullptr, as is the convention elsewhere.
…array if the bailout kind tells us to bail out on helper calls.
This change promotes several asserts to failfasts, and adds two additional ones, in order to ensure that no post-lower opcodes are added earlier than the lowerer phase, either by being added to the incoming bytecode buffer, or by corrupting a part of the IR during the earlier phases of the JIT.

…l list instead of parse node index.
…async arrow function.
The MissingItem check is happening on the array in a loop. It is possible that we get called into script and that mutates the array. So the Array's head is newly created with length. However the loop is still performing over the old length. Fixed this by checking the length In IsMissingItem function. Added a unittest.
…n param scope In a function expression with name, where the name is captured in one of the param scope functions, if there is a function or var declaration with the same name as the function expression name we were marking the function expression name as shadowed. In non-eval case this causes issue because the name symbol won't get added to the body. This change is to fix it in such a way if the name is captured in the param scope then we split the param and body scope such that the name symbol is added to the param scope not body scope.
