Justin Lebar ed1e312f05 [NVPTX] Remove NVPTXFavorNonGenericAddrSpaces pass. 
Summary:
This has been replaced by the NVPTXInferAddressSpaces pass.  We've had
the new one as the default with the old one accessible via a flag for
some months now, and we've had no problems.

Justin Lebar ed2c282d4b [NVPTX] Add intrinsics for shfl instructions. 
Summary:
Currently clang emits these instructions via inline (volatile) asm in
the CUDA headers.  Switching to intrinsics will let the optimizer reason
across calls to these intrinsics.
