Implemented for the Cranelift interpreter: - `Bitrev` to reverse the order of the bits in an integer. - `Cls` to count the leading bits which are the same as the sign bit in an integer, yielding one less than the size of the integer for 0 and -1. - `Clz` to count the number of leading zeros in the bitwise representation of the integer. - `Ctz` to count the number of trailing zeros in the bitwise representation of the integer. - `Popcnt` to count the number of ones in the bitwise representation of the integer.
