	is of unknown type or is inferred to be a derived type, set the
	primary and symbol TKR appropriately.

	selectors transmit the correct arrayspec to the associate name.
	(resolve_select_type): If the selector is an associate name of

	name should have its typespec. Simplify the conversion of a

	ref transfers the typespec from the symbol to the expression.

	PR fortran/86268
	* decl.cc (gfc_get_pdt_instance): Set the PDT instance field
	'f2k_derived', if not set already, to point to the given
	PDT template 'f2k_derived' namespace in order to give the
	PDT instance referential access to the typebound procedures
	of the template.
	* gfortran.h (gfc_pdt_is_instance_of): Add prototype.
	* resolve.cc (resolve_typebound_procedure): If the derived type
	does not have the attribute 'pdt_template' set, compare the
	dummy argument to the 'resolve_bindings_derived' type like usual.
	If the derived type is a 'pdt_template', then check if the
	dummy argument is an instance of the PDT template. If the derived
	type is a PDT template, and the dummy argument is an instance of
	that template, but the dummy argument 'param_list' is not
	SPEC_ASSUMED, check if there are any LEN parameters in the
	dummy argument. If there are no LEN parameters, then this implies
	that there are only KIND parameters in the dummy argument.
	If there are LEN parameters, this would be an error, for all
	LEN parameters for the dummy argument MUST be assumed for
	typebound procedures of PDTs.
	(resolve_pdt): Add a check for ALLOCATABLE and POINTER attributes for
	SPEC_DEFERRED parameters of PDT class symbols.  ALLOCATABLE and
	POINTER attributes for a PDT class symbol are stored in the
	'class_pointer' and 'allocatable' attributes of the '_data'
