+C Loading with unaligned movq's costs an extra 1 c/l and hence is avoided.
+C Two movd's and a punpckldq seems to be the same speed as an aligned movq,
+C and using them saves fiddling about with alignment testing on entry.
+C
+C For popcount there's 13 mmx instructions in the loop, so perhaps 6.5 c/l
+C might be possible, but 8 c/l relying on out-of-order execution is already
+C quite reasonable.
