Fix for PR debug/41266

ChangeLog:

	* include/dwarf2.h (enum dwarf_tag): Add
	DW_TAG_template_parameter_pack and DW_TAG_formal_parameter_pack.

gcc/ChangeLog:

	* dwarf2out.c (template_parameter_pack_die,

	(make_ith_pack_parameter_name): Remove this function.
	(dwarf_tag_name): Support printing DW_TAG_template_parameter_pack and
	DW_TAG_formal_parameter_pack.
	(gen_generic_params_dies): Represent each template parameter pack
	by a DW_TAG_template_parameter_pack DIE. Argument pack elements are
	represented by usual DW_TAG_template_*_parameter DIEs that are
	children of the DW_TAG_template_parameter_pack element DIE.
	(generic_parameter_die): This doesn't deal with parameter pack
	names anymore. Don't generate DW_AT_name for some DIEs, e.g. children of
	parameter pack DIEs.

	in certain cases, e.g. for pack elements.
	(gen_formal_types_die, gen_decl_die): Adjust usage of
	gen_formal_parameter_die.
	(gen_subprogram_die): Represent each function parameter pack by a
	DW_TAG_formal_parameter_pack DIE. Arguments of of the pack are
	represented by usual DW_TAG_formal_parameter DIEs that are children
	of the DW_TAG_formal_parameter_pack DIE. Remove references to
	____builtin_va_alist decls as no part of the compiler uses those
	anymore.
	* langhooks.h (struct lang_hooks_for_decls): Add
	function_parm_expanded_from_pack_p, get_generic_function_decl
	and function_parameter_pack_p hooks.  Fix comment for
	get_innermost_generic_parms hook.

	LANG_HOOKS_FUNCTION_PARM_EXPANDED_FROM_PACK_P,
	LANG_HOOKS_GET_GENERIC_FUNCTION_DECL): Initialize these
	hooks for the c++ FE.

	(template_args_variadic_p, make_ith_pack_parameter_name): Add a new
	line between comment and function.
	(get_template_argument_pack_elems): Fix comment.
