Bswap32 returns its input with byte order reversed 0x01020304 -> 0x04030201
Bswap64 returns its input with byte order reversed 0x0102030405060708 -> 0x0807060504030201
Ctz32 counts trailing (low-order) zeroes, and if all are zero, then 32.
Ctz64 counts trailing (low-order) zeroes, and if all are zero, then 64.
Ctz8 returns the number of trailing zero bits in x; the result is 8 for x == 0.
LeadingZeros64 returns the number of leading zero bits in x; the result is 64 for x == 0.
LeadingZeros8 returns the number of leading zero bits in x; the result is 8 for x == 0.
len64 returns the minimum number of bits required to represent x; the result is 0 for x == 0.
Len8 returns the minimum number of bits required to represent x; the result is 0 for x == 0.
OnesCount64 returns the number of one bits ("population count") in x.
TrailingZeros64 returns the number of trailing zero bits in x; the result is 64 for x == 0.
TrailingZeros8 returns the number of trailing zero bits in x; the result is 8 for x == 0.
