<pre>While running the test-release.sh on Ubuntu 16.04, the test-suite run fails on
'SingleSource/UnitTests/Vector/AVX512F/Vector-AVX512F-t_movzext.test'.
The build machine I used has a skylake CPU (Silver 4114). My previous builds
of llvm+clang on Ubuntu 16 were usually on a much older AMD CPU that would have
not had support for this AVX512 test case.
Because of the test's description and the failure mode, I've speculated that
this is a codegen failure.
