WebglConformance_deqp_functional_gles3_textureshadow_2d_array_nearest_greater goes into infinite loop if GPU process crashes

Project Member Reported by kbr@chromium.org, Sep 19 2016 
The WebGL 2.0 conformance test WebglConformance_deqp_functional_gles3_textureshadow_2d_array_nearest_greater seems to go into an infinite loop if the GPU process crashes. Here is an example:

https://build.chromium.org/p/tryserver.chromium.mac/builders/mac_optional_gpu_tests_rel/builds/3515

https://chromium-swarm.appspot.com/user/task/315bbcf274131e10

Here's an excerpt from the log. The entire log of the shard is attached.

Probably the harness needs to be made more robust to lost contexts (though they really should not happen during test execution).

kbr: since you filed this, can you recommend what to do with this bug? Is it still worth investigating?

We need to try removing the flaky expectations for these tests and see whether they're reliable now. Hopefully they will be.
