* gprof.c (long_options): Add "--function-ordering" and

	"--file-ordering" options.
	(usage): Add new options to usage message.
	(main): Handle new options.
	* gprof.h (STYLE_FUNCTION_ORDER): Define.
	(STYLE_FILE_ORDER): Define.
	(function_mapping_file): Declare.
	* cg_arcs.c (arcs, numarcs): New globals.

	(arcs, numarcs): Declare new globals.
	* core.c (symbol_map, symbol_map_count): New globals.
	(read_function_mappings): New function to read in a function
	to object map file.
	(core_init): Call read_function_mappings if a function mapping
	file exists.
	(core_create_function_syms): Handle function to object file
	mappings.
	* symtab.h (struct sym): New fields "mapped", "has_been_placed",
	"nuses", "prev".
	* cg_print.c (cmp_arc_count): New function for sorting arcs.
	(cmp_fun_nuses): Likewise for functions.
	(cg_print_function_ordering): New function to print a suggested
	function ordering.
	(cg_print_file_ordering): Likewise for ordering .o files.
