Ongoing benchmark graphs

We've just started running a weekly benchmark of GCC trunk and Linaro GCC tip. I've written a short script that compares against a baseline and spits out a graph: http://ex.seabright.co.nz/benchmarks/gcc-4.8~svn.png http://ex.seabright.co.nz/benchmarks/gcc-linaro-4.7%2bbzr.png

I'll switch the baseline to GCC 4.7.0 once the build and benchmark run completes. The gcc-linaro results need more data before they'll make sense.

Part way there. An automatic email would be next. We should check the graphs before each performance call.
