[HIPIFY] Current trunk LLVM 7.0 initial support

Tested with CUDA 8.0, 9.0, 9.1 and 9.2.

Only 8.0 works with LLVM 7.0, due to the changes in LLVM trunc since released 6.0, which works fine with CUDA 8.0 and 9.0.

So, nothing to do in hipify-clang, hope that all the CUDA 9.x related issues will be fixed in 7.0 release.
