[turbofan] Combine GenericLoweringPhase and ChangeLoweringPhase.

[turbofan] Combine GenericLoweringPhase and ChangeLoweringPhase.

There's no need to use a dedicated ChangeLoweringPhase before we go to
GenericLoweringPhase; instead that change lowering (which is really
simplified lowering by now) should run together with generic lowering.

Hey Jaro,

No need to have this sequentially, can run together instead.
Please take a look.

Thanks,
