Lighting shader outputs black when normals are (0, 0, 1)

Project Member Reported by dvonbeck@google.com, Jul 7 2016 
Identified on GPUs Adreno420, Mali400, Mali400MP2, SGX554. Probably caused by low floating-point precision when branching due to division-by-zero check.

What steps will reproduce the problem?
(1) Run lightingshader GM on a device with these GPUs

What is the expected output?
The surface being lit correctly

What do you see instead?
Just black
