Subject: Micro optimize move_is_ep() and move_is_castle()
X-Git-Url: https://git.sesse.net/?p=stockfish;a=commitdiff_plain;h=da91fab8cbc2dc4dfb1dc6e1e56fbe71ee6a893e;hp=6176357ac18dcc2f0dd12c17d5ac654c86a32009

Micro optimize move_is_ep() and move_is_castle()

Avoid a shift operation moving it at compile time.

No functional change.
