BENCH CHANGE! Switch to new loop cycle

Test new loop cycle in probe_ab()
...
Currently we return as soon as we reach
beta. This makes the bench signature to
depend on the move order in case we have
more than one possible capture and only
one of them reach beta then the nodes
searched are different in case we first
test one capture or the other.
Verify that the best value found by the
two move llops are the same. This check
will allow to remove old loop, replaced
by new one.

Fix sorting of leading pawns
...
Currently we sort leading pawns before
to flip. This is ok becuase MapPawns[] is
(almost) flip invariant apart for the case
of two symmetric non-leading pawns like the
case of d2, e2, h2.
After MapPawns[] sorting we have h2, d2, e2
with values 46, 11, 10. Then we flip because
leading pawns is in h2 -> a2,e2,d2 with values
46,10,11. So this is not sorted anymore.
The fix is to sort after flipping. And instead
of forst sorting just pick the leading pawn
directly.
