ptal. I'm pretty sure this will make CLs like
https://codereview.chromium.org/2514243003/ go smoothly

So try running this script.  It generates json with null values which isn't what
we want.

I can't actually run the script due to
https://bugs.chromium.org/p/chromium/issues/detail?id=667435.

I think we *do* actually want to have null values in here, as that is where this
logic kicks in:
https://chromium.googlesource.com/chromium/tools/build/+/refs/heads/master/sc....

We can actually try this out with a tryjob, let me cook one up.

cd into tools/perf the timing file is in that dir not in src.  Sorry about that.
