I think isolate.py is not happy with this structure (based on isolation errors
on try bots).

Afaik, isolate.py doesn't support nested conditions. (Does gyp support them? My
gyp knowledge is ~= 0).

You're absolutely right. I forgot to re-test locally after making this change.

There were a few other problems in this isolate, and it apparently triggered a
bug in isolate.py which I've worked around. Let's see if the latest round of try
jobs run successfully.
