A quick toolchain benchmark

I had a quick go at benchmarking the Linaro GCC compiler and was
presently surprised. The workload was decoding 10 s of h.264 video
using ffmpeg with assembly optimisations disabled. This gives the
compiler a good workout.
Compared to FSF GCC 4.4.4, Linaro GCC 4.4 is 6 % faster, FSF GCC 4.5.0
is 12 % faster, and Linaro GCC 4.5 is 24 % faster.
Now this is with a sample size of one so the results are not
statistically valid, and I haven't told you how to reproduce it so
they're not scientifically valid, but the numbers are pleasing none
