Benjamin Kramer d822892455 Add a DAGCombine to turn (ctpop x) u< 2 into (x & x-1) == 0. 
This shaves off 4 popcounts from the hacked 186.crafty source.

This is enabled even when a native popcount instruction is available. The
combined code is one operation longer but it should be faster nevertheless.
