Travis - Automatically test both LLVM35 and LLVM40 (#325)

* Travis: Add LLVM35, do not use the Clang static analyzer when using LLVM < 4.0.0

* Travis: Use sudo when cleaning up between tests (see details).

Installing with 'sudo make install' leaves some files that are
owned by root in the build folders.
