It would appear that the guessed counts are getting changed

Any trail of breadcrumbs to follow through the forest would be helpful

the use of aligned_alloc(). Now fixed to use posix_memalign if

The test passes on x86_64 and on ppc64le with -mcpu=power6. It will not

This patch allows the use of unaligned vsx loads/stores for builtin
expansion of memset and memcmp on p8/p9. Performance of unaligned vsx
instructions is good on these processors.

Here's the final version of this, which is committed as 256351.

I'll check the runtime of that --- I added some test cases to memcmp-
1.c and probably it is now taking too long. I will revise it so it's no
longer than it was before.

This brings it back not quite to where it was but a lot more reasonable

Jeff,
Thanks for sticking with this and reviewing, I have re-checked that

Bottom line is net improvement for CPU2017 int compared with either
current trunk, or disabling parallel reassociation. For CPU2017 fp,
very small overall degradation.
