By reverting r323281 locally, on top of rc2, I was now able to build and test 
for i386-freebsd11 too.

Main test results on amd64-freebsd11 look better, roughly 2000 less failures, 
mostly due to the libc++ get_timespec fix:

  Expected Passes: 52409 (rc1: 50388)
  Expected Failures  :   232 (rc1:   233)
  Unsupported Tests  :  3687 (rc1:  3687)
  Unexpected Passes  : 1 (rc1: 1)
  Unexpected Failures:   491 (rc1:  2490)

Test-suite test results on amd64-freebsd11:

  Expected Passes: 845
  Unexpected Failures: 61

Test results on i386-freebsd11:

  Expected Passes: 50186
  Expected Failures  : 226
  Unsupported Tests  : 2502
  Unexpected Failures: 306

Unfortunately the test-suite doesn't build on i386, since quite a few of its 
components requires SSE2, and the build shows many errors like:

/home/dim/llvm/7.0.0/rc2/test-suite.src/Bitcode/Benchmarks/Halide/blur/driver.cpp:37:29:
 error: always_inline function '_mm_set1_epi16' requires target feature 'sse2', 
but would be inlined into function 'blur_fast' that is compiled without support 
for 'sse2'
__m128i one_third = _mm_set1_epi16(21846);

 Since it's been doing this for a number of years now, I don't think it 
 would be bad at all, at least not for FreeBSD.  At least, a lot more 
 effort is needed to supply properly working atomic libcalls for 64 bit 
 values on i386.  (They can't be implemented without at least a bit of 
 kernel assistance.)

I've now filed .
