This patch bridges the gap between the recent epilogue vectorisation
patches and https://gcc.gnu.org/ml/gcc-patches/2019-10/msg01822.html .
I don't have any evidence that the series is independently useful,
but it shouldn't make things worse either.

Tested individually on aarch64-linux-gnu and as a series on
x86_64-linux-gnu.  OK to install?

Richard
