Last night's compilation at -O1 with my hacks applied finished after
a whopping >6 hours. Top compile time consumers:
early inlining heuristics: 12409.92 (55%) usr
integration : 1417.65 ( 6%) usr
tree eh : 1140.75 ( 5%) usr
tree PTA : 309.46 ( 1%) usr
tree SSA incremental : 6065.43 (27%) usr
tree split crit edges : 515.67 ( 2%) usr
TOTAL : 22448.04
Peak memory: 4294647808 (~4GB).
