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
