[Patch, Fortran, OOP] PR 54917: [4.7/4.8 Regression] TRANSFER on polymorphic variable causes ICE

[Janus Weil]

Hi all,

the attached patch implements support for polymorphic arguments to
TRANSFER. For details and discussion see the PR.

The patch was regtested successfully on x86_64-unknown-linux-gnu. Ok for trunk?

Btw, as part of the PR is a regression in 4.7 and trunk, I would like
to backport the target-memory.c part and the first test case to the
4.7 branch. Ok?

Cheers,
Janus
