Remove make_bitboard() In current master, the function make_bitboard() does nothing apart from helping initialize the SquareBB[] array. This seems like an unnecessary abstraction layer. The advantage of make_bitboard() is we can define a bitboard, in a simple and general way, not only from a single square but also from a list of squares. It is more elegant, faster and readable than combining multiple SquareBB explicitly, but the last complex use case in evaluation was simplified away a few months ago. If make_bitboard() becomes useful again to define complicated bitboards, it will be easy enough to reintroduce it using this pull request as an implementation reference. No functional change.
