The first version of this had a big bug and cleared past the requested bytes.
This version passes regstrap on ppc64le(power7/8/9), ppc64be(power6/7/8),
and ppc32(power8).
OK for trunk (and 8 backport after a week)?
Thanks!

When I previously added the use of unaligned vsx stores to inline expansion
of memset, I didn't do a good job of managing boundary conditions. The intention
was to only use unaligned vsx if the block being cleared was more than 32 bytes.
What it actually did was to prevent the use of unaligned vsx
