Subject: Don't update pieceCount for ALL_PIECES
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=64a71c3c02bdadfa80bed50fe5ba96984328627a

Don't update pieceCount for ALL_PIECES

It is currently unused and only adds
overhead for nothing.

Also set proper type of chess960.

No functional change.
