Failing sasmodels unit tests on Intel(R) Iris(TM) Graphics 6100

[wojciech]

Three sasmodels unit tests are failing on my hardware: Intel® Iris™ Graphics 6100 Mac OSX 10.11. They work fine on CPU when compiled both with dll and opencl. I am running tests from sasmodels dir:
python -m sasmodels.model_test all

These tests fails on single precision. single=False makes them pass but this is not what we want.

This might be fixed with updated drivers from Intel. Tests which were failing on an Intel HD 630 are passing after installing the latest driver on linux (r5.0.63503).
