Justin Lebar 21e5d4fcfa [CUDA] Invoke ptxas and fatbinary during compilation. ... Summary: Previously we compiled CUDA device code to PTX assembly and embedded that asm as text in our host binary. Now we compile to PTX assembly and then invoke ptxas to assemble the PTX into a cubin file. We gather the ptx and cubin files for each of our --cuda-gpu-archs and combine them using fatbinary, and then embed that into the host binary. Adds two new command-line flags, -Xcuda_ptxas and -Xcuda_fatbinary, which pass args down to the external tools.
