Test Cases Only

Hello,

I'm wondering whether a quick and dirty hack
that would keep derived type data per class
array declaration could work, coarrays are
excluded at the moment (I know nothing about). 

The attached file contains only test cases for
this PR. The first of them demonstrates what
the hack could do. Let's see the vtab names:

current vtab name: __class_m_T_1_0a
hacked  vtab name: __class_m_T_1_0a_b.sub2.m

Where 'b' is a class array of type 'T' in the
subroutine 'sub2', which in turn is in module
'm'.
