/* Precomputed masks for the iota transform.
 *
 * Each round uses a 64-bit mask value. In each mask values, only
 * bits whose position is of the form 2^k-1 can be set, thus only
 * 7 of 64 bits of the mask need to be known for each mask value.
 *
 * We use a compressed encoding of the mask where bits 63, 31 and 15
 * are moved to bits 4-6. This allows us to make each mask value
 * 1 byte rather than 8 bytes, saving 7*24 = 168 bytes of data (with
 * perhaps a little variation due to alignment). Decompressing this
 * requires a little code, but much less than the savings on the table.
 *
 * The impact on performance depends on the platform and compiler.
 * There's a bit more computation, but less memory bandwidth. A quick
 * benchmark on x86_64 shows a 7% speed improvement with GCC and a
 * 5% speed penalty with Clang, compared to the naive uint64_t[24] table.
 * YMMV.
