GetNativeDataPropertyByValuePure was showing up in isConcatSpreadable in matrix-react-bench. It was looking up a constant symbol on the object - in this case, we can fold it the offending MMegamorphicLoadSlotByValue into MMegamorphicLoadSlot, which will let us inline it and turn the id and the id hash into immediates. It's a small win.
