PR fortran/78990
* expr.c (gfc_is_class_array_function): Renamed from
'gfc_is_alloc_class_array_function' and modified to return true
for pointers as well as allocatable results.
* gfortran.h : Change of name for prototype of above function.
* trans-array.c (gfc_add_loop_ss_code): Force finalization of
class array results.
(build_class_array_ref): Change assertion into a condition.
(build_class_array_ref): Set the se class_vptr for class array
function results.
(gfc_walk_function_expr): Reference gfc_is_class_array_function
as above.
* trans-decl.c (get_proc_result): Move it up before
gfc_trans_deferred_vars.
(gfc_trans_deferred_vars): Nullify explicit return class arrays
on entry.
* trans-expr.c (gfc_conv_class_to_class): Allow conversion of
class array functions that have an se class_vptr and use it
for the result vptr.
(gfc_conv_subref_array_arg): Rename reference to the above
function.
(gfc_conv_procedure_call): Ditto. Add the se pre block to the
loop pre block before the function is evaluated. Do not
finalize class pointer results.
(arrayfunc_assign_needs_temporary, gfc_trans_assignment_1) More
renamed references.
* trans-intrinsic.c (gfc_conv_intrinsic_size): Ditto.
