func Bswap32(x uint32) uint32
Bswap32 returns its input with byte order reversed 0x01020304 -> 0x04030201
func Bswap64(x uint64) uint64
Bswap64 returns its input with byte order reversed 0x0102030405060708 -> 0x0807060504030201
func Ctz32(x uint32) int
Ctz32 counts trailing (low-order) zeroes, and if all are zero, then 32.
func Ctz64(x uint64) int
Ctz64 counts trailing (low-order) zeroes, and if all are zero, then 64.
func Ctz8(x uint8) int
Ctz8 returns the number of trailing zero bits in x; the result is 8 for x == 0.
