I've built and tested for FreeBSD 11 (a.k.a 11-STABLE) this time, since
FreeBSD 10 will be going EOL pretty soon now.  Uploaded:

SHA256 (clang+llvm-7.0.0-rc1-amd64-unknown-freebsd11.tar.xz) = ed3191635be26cced8c75d5e57ff7e559f44b927a64c10d22611d8d912cf6df4

I posted the full test results here:

https://gist.github.com/DimitryAndric/64e9a7805a01e6027e2aaabfcda42bed

Summary:
  Expected Passes    : 50388
  Expected Failures  : 233
  Unsupported Tests  : 3687
  Unexpected Passes  : 1
  Unexpected Failures: 2490

The failures are distributed as follows:

  2028 libc++
   205 AddressSanitizer-i386-freebsd-dynamic
   200 AddressSanitizer-x86_64-freebsd-dynamic
    20 XRay-Unit
    11 MemorySanitizer-Unit
     7 lldb-Suite
     4 libunwind
     3 XRay-x86_64-freebsd
     3 lldb
     2 ThreadSanitizer-x86_64
     2 UBSan-MemorySanitizer-x86_64
     2 libFuzzer
     1 SanitizerCommon-asan-i386-FreeBSD
     1 SanitizerCommon-asan-x86_64-FreeBSD
     1 libomp

Almost all libc++ failures are due to FreeBSD missing timespec_get(),
and this became mandatory with https://reviews.llvm.org/rL338419:

      ~~^~~~~~~~~~~~

       ^

We're tracking this in FreeBSD here: https://bugs.freebsd.org/230400,
but for existing FreeBSD releases this isn't fixable, so we could really
use some sort of workaround in libc++. :-)
