<pre>Resolving as invalid. This looks to have been compiled without enabling support
CRC32 feature either through -march or -mcrc32. We generally tell people not
use the builtin directly and instead to use the intrinsic in x86intrin.h
At the time this was filed using the intrinsic should have given a compile
error that the intrinsic wouldn't be defined without enabling crc32. Current
version of clang should detect the missing feature support on the builtin even
without using the intrinsic.</pre>
