Preserve argument order to (==)/eq in nub and nubBy
This makes nub and nubBy behave as specified in the Haskell 98 Report.
This reverts 0ad9def53842e86fb292eccb810190711c42d7c5, and
fixes #3280, #7913 and #2528 (properly).
Before this change, the output of `T2528` was (4x wrong):
```
[A,B]
[1,2]
False
False
```
