This is a revised version of the patch series posted at
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/553919.html

Patch 8/8 in particular changes rather a lot more than the original
!speed changes.  Bootstrapped and regression tested powerpc64le-linux
and powerpc64-linux biarch.

Hi Segher,
I've been holding off pinging these knowing you had a lot of other
review work, but maybe that's settling down now?  You already OK'd
1/8, 2/8 and 6/8.
