This CL fixes several scoping/context issues: * Do not reuse scopes in SequenceNode_s as they might introduce a new context level. In that case we would trigger context allocationg multiple times resulting in scope/contexts being out of sync. * Properly save and restore saved_try_context in try/catch/finally blocks and nesting closures. For this we need to keep track of async closures top scopes.
