* trans-array.c (gfc_array_init_size): Add two extra arguments
to convey the dynamic element size of a calls object and to
return the number of elements that have been allocated.
(gfc_array_allocate): Add the same arguments and use them to
call gfc_array_init_size. Before the allocation dereference
the data pointer, if necessary. Set the allocated array to zero
if the class element size or expr3 are non-null.
* trans-expr.c (gfc_conv_class_to_class): Give this function
global scope.
(get_class_array_ref): New function.
(gfc_copy_class_to_class): New function.
* trans-array.h : Update prototype for gfc_array_allocate.
* trans-stmt.c (gfc_trans_allocate): For non-variable class
STATUS expressions extract the class object and the dynamic
element size. Use the latter to call gfc_array_allocate and
the former for setting the vptr and, via
gfc_copy_class_to_clasfc_cs, to copy to the allocated data.
* trans.h : Prototypes for gfc_get_class_array_ref,
gfc_copy_class_to_class and gfc_conv_class_to_class.
