[Patch, Fortran, F03] PR 54285: Calling a PPC with proc-ptr result

[Janus Weil <janus at gcc dot gnu dot org>]

Hi all,

here is another proc-ptr patch, which allows to submit calls to
procedure-pointer components which have a procedure-pointer result.
This sounds a bit twisted (and I guess one has to suffer from some
very special form of mental illness in order to feel the urge to do
something like this), but apparently it is allowed by the standard,
and by chance I came across it recently.

Fortunately the patch is rather straightforward and just makes some
minor adjustments in the corresponding parsing and checking routines.
Regtested on x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
