D13613: RFC: Fix libclang default include paths on FreeBSD.

  On my system,
  
    > find /usr/lib64/ -name vadefs.h
    /usr/lib64/clang/6.0.0/include/vadefs.h
    > find /usr/lib64/ -name varargs.h
    /usr/lib64/clang/6.0.0/include/varargs.h
    /usr/lib64/gcc/x86_64-suse-linux/8/include/varargs.h
  
  Meaning that with `vadefs.h` we wouldn't be able to exclude the GCC builtin directory. The intersection of both on my system is:
  
    > sort <(ls /usr/lib64/clang/6.0.0/include/) <(ls /usr/lib64/gcc/x86_64-suse-linux/8/include/) | uniq -d

  Maybe you can intersect that with the files on your system, so that we can find a better candidate.

My understanding is that this is primarily supposed to exclude non-Clang builtin directories, especially the GCC builtin directory which Clang might not understand.
