Artem Belevich 34f481acc6 [CUDA] Detect and link with CUDA's libdevice bitcode library. 
- added detection of libdevice bitcode file and API to find one appropriate for the GPU we're compiling for.
- pass additional cc1 options for linking with detected libdevice bitcode
- added -nocudalib to prevent automatic linking with libdevice
- added test cases to verify new functionality

Artem Belevich fa11ab53c0 [CUDA] added include paths for both sides of CUDA compilation. 
In order to compile a CUDA file clang must be able to find
include files for both both host and device.

This patch passes AuxToolchain to AddPreprocessingOptions and
uses it to add include paths for the opposite side of compilation.

We also must be able to find CUDA include files. If the driver
found CUDA installation, it adds appropriate include path
to CUDA headers. This can be disabled with '-nocudainc'.

- Added include paths for the opposite side of compilation.
- Added include paths to detected CUDA installation.
- Added -nocudainc to prevent adding CUDA include path.
- Added test cases to verify new functionality.

Artem Belevich 7d6266ead3 Disabled one of the test runs in cuda-detect.cu 
--sysroot apparently can't handle long paths which triggers test
failure on some platforms.

Artem Belevich 98607b6757 [CUDA] Added CUDA installation detector class. 
Added new option --cuda-path=<path> which allows
overriding default search paths.
If it's not specified we look for CUDA installation in
/usr/include/cuda and /usr/include/cuda-7.0.

Artem Belevich 8d20bd3917 Reverted r248408 "[CUDA] Added CUDA installation detector class." 
because included test fails on some platforms.
