re PR fortran/78990 (ICE when assigning polymorphic array function result)

2017-11-19  Paul Thomas  <pault@gcc.gnu.org>

	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.
