* trans-array.cc (get_array_ref_dim_for_loop_dim): Use the arg1
class container carried in ss->info as the seed for a lhs in
class valued transformational intrinsic calls that are not the
rhs of an assignment. Otherwise, the lhs variable expression is
taken from the loop chain. For this latter case, the _vptr and
_len fields are set.
(gfc_trans_create_temp_array): Use either the lhs expression
seeds to build a class variable that will take the returned
descriptor as its _data field. In the case that the arg1 expr.
is used, 'atmp' must be marked as unused, a typespec built with
the correct rank and the _vptr and _len fields set. The element
size is provided for the temporary allocation and to set the
descriptor span.
(gfc_array_init_size): When an intrinsic type scalar expr3 is
used in allocation of a class array, use its element size in
the descriptor dtype.
* trans-expr.cc (gfc_conv_class_to_class): Class valued
transformational intrinsics return the pointer to the array
descriptor as the _data field of a class temporary. Extract
directly and return the address of the class temporary.
(gfc_conv_procedure_call): store the expression for the first
argument of a class valued transformational intrinsic function
in the ss info class_container field. Later, use its type as
the element type in the call to gfc_trans_create_temp_array.
