Marco Costalba 5f7d37273c Micro optimize generate_pawn_checks() ...

Use a better condition to find candidate direct check pawns.
In particular consider only pawns in the front ranks of the
enemy king, this greatly reduces pawns candidates bitboard
that now is empty more then 90% of the time so that we
can early skip further tests.

No functional change.
