As mentioned, the default packaging for Ubuntu might not be what you 
want.  There's http://apt.llvm.org/ - I haven't used it, I don't know if 
it uses libc++ and if it does, which abi is used. It recommends 
toolchain-test-r, which in my experience can break your system compiler 
and make it very hard to revert those changes.

I recommend you either build clang yourself, or take the builds from 
here: http://releases.llvm.org/download.html

You can just extract to any directory and clang will automatically find 
the extracted libc++ (which uses libc++abi).

If you prefer to build it yourself, something like this should be 
sufficient:

svn co 
http://llvm.org/svn/llvm-project/llvm/tags/RELEASE_400/final/utils/release

release/test-release.sh -release 4.0.0 -final -triple 
x86_64-linux-gnu-ubuntu-16.04
