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. Differential Revision: https://reviews.llvm.org/D42642 llvm-svn: 323848
