Adding screenshot of what the background colouring in sparklines based on binary hash values looks like. The screenshot shows that it's more straightforward to see what results are noise and which ones are probably real differences:

- The 14% performance swing in viterbi in the screenshot is just noise, as the program binary didn't change (same background colour).
- The 13% performance swing in sim is probably real: the binary changed since yesterday.
- hexxagon and sqlite3: the regressions are probably real. Both programs have oscillated a bit over the past week; i.e. the re-occurence of the same background colour indicates LLVM ToT's codegen for these programs has been identical on a few non-consecutive days.
- hash2: it's just noise, the binary hasn't changed for the past 10 days.
