[cfe-dev] Set cuda path default

[Jonas Hahnfeld via cfe-dev]

Hi Simone,

I don't think an environment variable was ever used in upstream trunk, I 
only remember seeing this in IBM's clang-ykt fork. However, I committed 
an improvement just yesterday: Clang will now try to find ptxas in $PATH 
and if it is in a directory called bin/, add that's parent directory as 
a candidate CUDA installation. I think this should work for most HPC 
systems that use environment modules to manage their CUDA 
installations...
Unfortunately, I still have to write documentation about this mechanism 
so you'd have to refer to the source code for details.

Cheers,
Jonas
