[Bug 100105] Make Theano OpenCL support work on Clover and RadeonSI

It looks like our vstore_half_rtn is not working as expected, which is weird because it passes CTS.

I take this back.

vstore_half_rtn rounds to negative infinity (towards 0 for positive numbers). Changing line 53 in cluda_opencl.h: - vstore_half_rtn(f, 0, &r.data); + vstore_half_rte(f, 0, &r.data);

fixes the two failures.

Other than advertising OCL1.2 the remaining failures are NOTOURBUG.
