[PATCH] CUDA host device code with two code paths

Can you remind me what the CUDA compilation model is currently? My memory was that the clang driver was eventually going to launch two -cc1 actions, one for device and one for host, presumably with different flags. I would expect that lib/Frontend/InitPreprocessor.cpp would define this macro when targeting the device.

If we're doing a single compilation with a fat object approach, we may need to do something weird to get this right. =/
