Can you reproduce on /projects/clang400-import@312309 or devel/llvm-devel after editing .sh file?

Yes, I can reproduce with clang 4.0.0 (branches/release_40 292009) (as in the clang400-import branch).  Investigating...
Comment 5 Dimitry Andric freebsd_committer 2017-01-17 19:23:32 UTC 
Minimized a test case, and submitted it upstream as https://llvm.org/bugs/show_bug.cgi?id=31672

Comment 7 Dimitry Andric freebsd_committer 2017-01-22 19:45:05 UTC 
After r312643, I can build graphics/gegl to completion now, with the SIMD option checked.
Comment 8 Jan Beich freebsd_committer 2017-01-23 00:12:04 UTC 
graphics/gegl3, like graphics/svgalib, is a blocker for x11/gnome3 metaport. It doesn't have SIMD option unlike graphics/gegl. Anyway, gegl3 builds fine now: http://sprunge.us/NPdF
