Function fill_array64

deps/jemalloc/test/src/SFMT.c:587–599

* This function generates pseudorandom 64-bit integers in the * specified array[] by one call. The number of pseudorandom integers * is specified by the argument size, which must be at least 312 and a * multiple of two. The generation by this function is much faster * than the following gen_rand function. * * For initialization, init_gen_rand or init_by_array must be called * before the fi

 * returns the pointer to the aligned memory block.
