[tremor] [PATCH] 12% global performance gain on a StrongARM

It's the worst case that we want to optimize, not the common case. Doesn't matter how much you optimize for the most common cases, the CPU will still have to be dimensioned to handle the worst case.

Still, looks good.
What's the performance difference on the ARM7?
