      We need to move popcnt instruction implementation out of s390.ad file as it is required to be required some methods present in JDK-8331126.

      Currently z_popcnt instruction will behave differently if used by hardware older than z15, as they don't have Miscellaneous-Instruction- Extensions Facility 3.
