Dear all,

commit r11-1235 for pr95331 addressed array bounds issues with
unlimited polymorphic array dummies, but caused regressions for
CLASS array dummies that lead to either wrong code with bounds-checking,
or an ICE.  The solution is simple: add a check whether the dummy
is unlimited polymorphic and otherwise restore the previous behavior.

The attached patch regtested fine on x86_64-pc-linux-gnu and was
OK'ed in the PR by Jerry.

Pushed as: r14-8471-gce61de1b8a1bb3

Since this is a 11/12/13/14 regression and appears safe otherwise,
I intend to backport as suitable, unless there are comments.

Thanks,
Harald
