Here is the average of three runs:
flags: -O2 -funroll-loops -ffast-math
WITH PATCH WITHOUT PATCH
real 83m54.488s 79m35.982s
usr 3m38.307s 3m37.057s
sys 0m27.477s 0m24.467s
assembly
code 8,643,479 8,649,104
size
(bytes)
Ah, thrashing. Anyway, this shows a compile time (usr time) increase of
roughly 0.58% which was fairly consistent over all three runs and a code
size improvement of 0.07%.

Here is the average of three runs:
flags: -O3
WITH PATCH WITHOUT PATCH
real 0m21.108s 0m20.944s
usr 0m17.293s 0m17.347s
sys 0m1.470s 0m1.583s
assembly
code 4139 4139

No code size improvement and a slight decrease in compile time (roughly
0.31%). However, since one was not consistently faster than the other
over the three runs, I'm assuming that this is just noise.
