Alan Coopersmith 6b857b7899 dix: Use __builtin_popcountl if available to replace Ones() ...

If the compiler knows of a better algorithm for counting the number of
bits set in a word for the target CPU, let it use that, instead of the
classic algorithm optimized for PDP-6.

Based on xorg/lib/libxext@490a25e6f8a4d2482af4364c700b68ad11a4d10b
