Performance refactor of
AddClosureParamTypeForArrayMapRectorandAddClosureParamTypeForArrayReduceRector. No behavior change - all fixtures pass unchanged.Both rules resolved the function reflection via
resolveFunctionLikeReflectionFromCall()before checking that the closure argument is actually aClosurenode. That reflection resolution was paid even for the common cases where the callback is a string callable or an arrow function, which can never match.The cheap structural guard (closure arg present and is a
Closure) is now hoisted above the reflection call. Both conditions are required anyway, so reordering is safe; reflection is only resolved once the closure arg is confirmed.
