I will be merging mem-ssa into mainline over the next few days. The experiments that I have been doing show marked improvements in compile times over the set of programs that I have in my sandbox. The compiler should now be between 5% and 25% faster.

Here's a summary of the speedups I obtained with respect to mainline
@119145.

Oh. Uh, 119145 was before the rechanging of the alias analysis stuff.

This patch had significant performance impact on tramp3d and other cases.
So sadly, you may want to retest if you really want to know *runtime
performance* numbers (I know this sucks).

Compile-time performance numbers are likely the same, so i wouldn't
bother there.
