* Bitops functions
* ================
*
* - The main test function performs several subtests.
* - Check bit operations on one core.
* - Initialize valXX to specified values, then set each bit of valXX
* to 1 one by one in "test_bit_relaxed_set".
*
* - Clear each bit of valXX to 0 one by one in "test_bit_relaxed_clear".
*
* - Function "test_bit_relaxed_test_set_clear" checks whether each bit
* of valXX can do "test and set" and "test and clear" correctly.
