For -O1, integration is slower in the mainline compared with 3.3.2, 2.46 vs 1.51.
global alloc is also slower: 3.21 vs 2.38.
Speeding those up will help.
This again on powerpc-darwin. The reason why I thought 3.3.2 was much slower than the mainline was
because the GC limits were low for 3.3.2 on darwin.
