Any initial feedback on the impact on compile-time? 1.5 regressed already
quite a bit, so I was wondering if SSA is going to help.

SSA is now able to compile 65% of the functions in make.bash.
Gcbits are being generated, so stack copying is working.
We still have to generate write barriers, so we have to run with GOGC=off
for now. Hopefully that will get fixed this coming week.
All the stdlib tests except the ones defeated by GOGC=off are working
(using the 65% SSA-compiled code and 35% old-compiler code).
