The trunk patch applied to GCC 7 and GCC 6 cleanly/no fuzz and it
bootstrapped and regtested with no regressions on powerpc64le-linux
as well as on powerpc64-linux and running the testsuite in both 32-bit
and 64-bit modes.

The backports were approved today, but I am leaving on vacation today,
returning on the 19th, so I will not commit the backports until I
return.  If there is a large need to have the backports committed before
I return, please work with Tulio to find someone on our GCC team to
commit the patch and watch for fallout.
