Note for ir.ii at -O0, we spend more time in local alloc and global alloc with the mainline than 3.3.2.
2.41 vs 3.86 and 3.74 vs 6.07 so someone who knows local alloc and global alloc might want to look
into this. This is on powerpc-darwin by the way, on x86, there might be a different problem someone
should do a -ftime-report with both the mainline and 3.4.x to see if this is also true on x86.
