be5ea3a651 Fixed CUDA mode for Clang/LLVM 9 upgrade 
- fix bug, which was caused by executing a transaction in the device
interpreter
- fixed warning from the device compiler
- update test cases

e47bb75f9f Allows to configure CUDA sm level for Cling CUDA tests 
- the CUDA sm level can be set via CLING_TEST_CUDA_SM_LEVEL
environment variable (e.g. "35"), before running the tests

b2bfd6e19f Extend the cling-test to deal with CUDA SDKs that are not in the default location 
- To enable the CUDA test, lit detects the `libcudart.so` in
`LD_LIBRARY_PATH`. Now lit also set the CUDA SDK root of
`libcudart.so` as cling parameter (`--cuda-path`) in the tests.
- Pass through the environment variable `CUDA_VISIBLE_DEVICES`.

9a4418b3c0 Improvements for Pull Request #240 
- little changes at comments and code style
- try to use const in IncrementalCUDADeviceCompiler, where is possible
- move CUDA device code compiler instance to IncrementalParser
- change the members of CuArgs to const and adjust the setCuArgs method
- use std::vector<string> instead llvm::Smallvector<const char *> to build argv for executeAndWait
- improve the error messages of generatePCH(), generatePTX() and generateFatbinary()
- replace m_Counter with a copy in IncrementalCUDADeviceCompiler to avoid involuntary changes
