Constexpr attacks (pext only) LLR: 2.97 (-2.94,2.94) <0.00,2.00> Total: 38400 W: 10057 L: 9749 D: 18594 Ptnml(0-2): 93, 4110, 10498, 4394, 105 https://tests.stockfishchess.org/tests/view/69d2073261a12cebe17edc04 compile time generation leads to sharing tables through the binary, resulting in gain on fishtest, as well as reduced memory usage. The downside is slightly longer compilation time. Using pdep reduces table size 4x, and gains a little outside of fishtest as well. closes https://github.com/official-stockfish/Stockfish/pull/6706 No functional change
