Okay, a new benchmark comparison. This time, it's asmgcc & Apple GCC 4.0 vs. 
shadowstack & Clang, both x86_64 builds. I'd say it's getting close to a tie: 
only three benchmarks show statistically significant results, from 4% to 15% 
slower.

Significantly different benchmarks:

### ai ###
Min: 0.423298 -> 0.474566: 1.1211x slower
Avg: 0.440061 -> 0.490685: 1.1150x slower
Significant (t=-9.968230, a=0.95)
Stddev: 0.02571 -> 0.02507: 1.0255x smaller

### meteor-contest ###

Stddev: 0.01273 -> 0.01097: 1.1610x smaller

### pyflate-fast ###
