These part are 4.0 regressions:
 tree alias analysis   :  24.22 ( 6%) usr   0.75 ( 2%) sys  26.57 ( 5%) wall
 tree PHI insertion    :   7.71 ( 2%) usr   1.26 ( 3%) sys   9.24 ( 2%) wall
 tree SSA rewrite      :  11.52 ( 3%) usr   4.32 (11%) sys  20.63 ( 4%) wall
 tree SSA other        :  21.33 ( 5%) usr   3.77 (10%) sys  27.79 ( 5%) wall
 tree operand scan     :  26.65 ( 7%) usr   3.78 (10%) sys  31.64 ( 6%) wall

These are most likely not:
 combiner              :  25.57 ( 6%) usr   0.20 ( 1%) sys  26.78 ( 5%) wall
 scheduling            : 211.44 (52%) usr   4.35 (11%) sys 225.27 (43%) wall
