I've sent the other CLs to Nico but I'd like to spread the load a bit.

Right now my goal is to run all tests that do have a .isolate always on
Swarming, never locally. There's 18 tests in this situation (partially running
on Swarming). After this patch, there's 7 tests always running on Swarming. For
a total of 25 tests.

There's 8 tests with a .isolate but not run on Swarming. I'll address them after
the 18 tests partially running on swarming.

There's 53 tests without a .isolate but before starting to fire on all sides, I
prefer to close up on the 25+8 tests that already have a .isolate file, then
I'll dig up the remaining tests.

Do you have a sense of how fast a test suite needs to be before it makes no
sense to run it under swarming? < 1 sec? < 10 seconds?

I'd say <10s. The goal to finish the conversion is not to performance but to
enable building on Win2K8 on GCE and run tests N times, once for each OS version
(XP, Win7, Win10). Similar thing for OSX.
