Andreas Kling 13680ae038 Kernel: Build with -O2 by default 
We used to build with -Os in order to fit within a certain size, but
there isn't really a good reason for that kind of restriction.

Switching to -O2 yields a significant improvement in throughput,
for example `test-js` is roughly 20% faster on my machine. :^)
