Match ECMA-262's SuperCall evaluation order by resolving the super constructor before evaluating the argument list. This preserves the constructor across argument-side prototype mutations and still lets abrupt argument evaluation happen before the constructor check. Add LibJS coverage and update bytecode baselines for the new saved super-constructor operand. The test262 superCallOrder staging test now passes.
