Again on top of the "v8 migration, powerpc improvements" series. I
don't plan to rebase the other way around since it's a lot of work.
So this is still in RFC until the other big series gets merged.

Thanks to Andrew for a lot of review. A submitted the likely s390x
bugs separately ahead of this series, and also disabled one of the
tests and dropped its fix patch as-per review comments. Hence 3 fewer
patches. Other than that, since last post:

* Tidied commit messages and added some of Andrew's comments.
* Removed the "SC2034 unused variable" blanket disable, and just
  suppressed the config.mak and a couple of other warnings.
* Blanket disabled "SC2235 Use { ..; } instead of (..)" and dropped
  the fix for it.
* Change warning suppression comments as per Andrew's review, also
  mention in the new unittests doc about the "check =" option not
  allowing whitespace etc in the name since we don't cope with that.

Thanks,
Nick
