Elsewhere in the Fortran front-end, the class_pointer attribute is
used for BT_CLASS entities instead of the pointer attribute. [...]This patch
follows suit for OpenACC. I couldn't actually come up with a test case
where this makes a difference (i.e., where "class_pointer" and "pointer"
have different values at this point in the code), but this may nonetheless
fix a latent bug.

Tested with offloading to AMD GCN. OK for mainline?

I think attr.pointer == true != attr.class_pointer only happens
for dummy arguments and select-type temporaries, neither of which
can occur for derived-type components.

Thus, I think it is not needed – but there are merits of having
consistency. Hence, OK.
