Subject: [PATCH 1/2] [CUDA] Improve clang's ability to detect recent CUDA
versions.
CUDA-11.1 does not carry version.txt which causes clang to assume that it's
CUDA-7.0, which used to be the only CUDA version w/o version.txt.
In order to tell CUDA-7.0 apart from the new versions, clang now probes for the
presence of libdevice.10.bc which is not present in the old CUDA versions.
This should keep Clang working for CUDA-11.1.
