[Patch, Fortran, OOP] Reject polymorphic arrays in 4.6

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

Hi all,

the 4.6 release is approaching in big steps and it will feature a lot
of OOP goodies. However, polymorphic arrays are still basically
unimplemented and I think the cleanest way to deal with this is to
reject dimensionful class variables altogether. This is what the
attached patch does.

I had to modify a few test cases which contain class arrays. Most of
them are just checking error messages, and none is actually "dg-do
run". I just commented out some stuff and added FIXME notes. Also I
would say we do not need a new test case here. Anyway it is only a
temporary rejection, and we will hopefully remove the error message as
soon as possible after the 4.6 release and start implementing class
arrays ...

Ok for trunk?

Cheers,
Janus
