Felix Kuehling a8a5960095 Add environment variable to disable GPU caching
This option may help debug synchronization or coherency issues
involving the GPU caches. It works only on dGPUs, by changing the
cache policy of the GPUVM default aperture to "cohrent", which is
implemented as non-cached on current dGPU hardware.
