[PATCH 04/18] alpha: Override READ_ONCE() with barriered implementation

I'd _really_ like to remove it, as I think it only serves to confuse people
on a topic that is confusing enough already. Paul's perfbook [1] already has
plenty of information about this, so I don't think we need to repeat that

* Implement Alpha's smp_load_acquire() using __READ_ONCE(), rather than

posted in November last year:
https://lore.kernel.org/lkml/20191108170120.22331-1-will at kernel.org/
I ended up parking the series while the READ_ONCE() implementation was
being overhauled, but with that merged during the recent merge window
and LTO patches being posted again [1], it was time for a refresh.
