multimedia/libvpx cause clang fatal error on CURRENT

[Iblis Lin]

Hi,

I got this while building multimedia/libvpx

```
cc -O2 -pipe -march=native ...
#0: t25: v8i64 = llvm.x86.avx512.psad.bw.512 TargetConstant:i64<5820>, t11, t5

fatal error: error in backend: Do not know how to split the result of this operator!

cc: error: clang frontend command failed with exit code 70 (use -v to see invocation)
FreeBSD clang version 6.0.0 (branches/release_60 321788) (based on LLVM 6.0.0)
Target: x86_64-unknown-freebsd12.0
Thread model: posix
InstalledDir: /usr/bin
```

My box:

FreeBSD abeing 12.0-CURRENT FreeBSD 12.0-CURRENT #0 r328198: Mon Jan 22 13:26:48
CST 2018 ***@abeing:/usr/obj/usr/src/amd64.amd64/sys/GENERIC amd64

Is this the same issue as
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=225488 ? That was
fixed in r328513. Please try that revision if you're not at it yet.
