crc32 on ppc64 (8131048)

[Vladimir Kozlov]

Hi,

We are reviewing crc32 implementation for SPARC currently and I looked on ppc code and found strange code for flag 
setting - it reset (set off) UseCRC32CIntrinsics flag immediately after setting it on:

http://hg.openjdk.java.net/jdk9/hs-comp/hotspot/file/f60b602209c7/src/cpu/ppc/vm/vm_version_ppc.cpp#l162

Is it intentional?

Thanks,
Vladimir
