util: Move util_is_power_of_two to bitscan.h and rename to util_is_power_of_two_or_zero
The new name make the zero-input behavior more obvious. The next patch adds a new function with different zero-input behavior. Signed-off-by: Ian Romanick <[email protected]> Suggested-by: Matt Turner <[email protected]> Reviewed-by: Alejandro PiƱeiro <[email protected]>
