If the CUDA toolkit is not installed to its default locations
in /usr/local/cuda, the user is forced to specify --cuda-path.
This is tedious and the driver can be smarter if well-known tools
(like ptxas) can already be found in the PATH environment variable.
Add option --cuda-path-ignore-env if the user wants to ignore
set environment variables. Also use it in the tests to make sure
the driver always finds the same CUDA installation, regardless
of the user's environment.

It passes --sysroot for the Linux CUDA installation. To make this test
pass when targetting Windows, you would need to pass
--sysroot=Inputs/CUDA-windows.

Summary:
This patch aims at removing redundancy in the way include paths for the regular and offloading toolchains are appended to the arguments list in the clang tool.

Summary:
Raise an error if you're using a CUDA installation that's too old for
the requested architectures. In practice, this means that you need a
CUDA 8 install to compile for sm_6*.
