Resolve dynamic identifier assignment targets before evaluating the right hand side, then store through that saved environment record. This matches the ECMA-262 ordering for simple assignment and var initializers when a with binding is deleted or direct eval creates a nearer var. Add runtime coverage for with and direct-eval cases and refresh bytecode expectations for dynamic assignments that now snapshot the binding before storing.
