[PATCH 0/3] OpenACC "exit data" copyout, and Fortran derived-type members

[Julian Brown]

This is a split version of the patch previously posted here:

  https://gcc.gnu.org/legacy-ml/gcc-patches/2020-01/msg00512.html

There were actually a couple of different issues addressed by that patch,
and Thomas raised another (or so).  This separated-out version should
be more-obviously safe (in terms of maintaining backwards compatibility,
where that makes sense).  Further commentary on individual patches.

Tested (as a series) with offloading to NVPTX. OK?
