gcc/ChangeLog:

	* dwarf2out.c (dwar2out_var_location): In addition to notes,
	process indirect calls whose target is compile-time known.
	Enhance pattern matching to get the SYMBOL_REF they embed.
	(gen_subprogram_die): Handle such calls.
	* final.c (final_scan_insn): For call instructions, invoke the
	var_location debug hook only after the call has been emitted.
