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).
