[Patch, Fortran, OOP] PR 56500: "IMPLICIT CLASS(...)" wrongly rejected

[Janus Weil]

Hi all,

here is a simple patch which fixes some problems with IMPLICT
CLASS(...) statements. Actually that's not a feature I would seriously
recommend anyone to use, but the Fortran standard allows it, so I
guess we should better support it ;)

The short patch attached here replaces all previous draft patches in
the PR and simultaneously fixes both comment 0 and 1. Regtested on
x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
