	* dwarf2.c (struct dwarf2_debug): Add inliner_chain member.
	(struct funcinfo): Add caller_func, caller_file, caller_line.
	tag, and nesting_level members.
	(lookup_address_in_function_table): Change first passed parameter
	from "struct funcinfo *" to "struct comp_unit *".
	(lookup_address_in_function_table): Dereference unit to find function
	table.
	(lookup_address_in_function_table): Traverse the function list to
	create a chain of inlined functions back to the first non inlined
	function.

	DW_AT_call_file and DW_AT_call_line.
	(comp_unit_find_nearest_line): Adjust lookup_address_in_function_table
	call to pass unit pointer instead of function table pointer.  For
	inlined functions, save pointer to the inliner chain.
	(_bfd_dwarf2_find_nearest_line): Initialize inliner_chain to NULL.
