[issue37295] Possible optimizations for math.comb()

Mark Dickinson added the comment: One approach that avoids the use of floating-point arithmetic is to precompute the odd part of the factorial of n modulo 2**64, for all small n. If we also precompute the inverses, then three lookups and two 64x64->64 unsigned integer multiplications gets
