Small cleanups before making collect2 use collect-utils.

* collect-utils.c (save_temps): New variable.
	(do_wait): Use it instead of debug.  Use fatal_error.
	* collect-utils.h (save_temps): Declare.
	* collect2.c (verbose): Rename from vflag.  All uses changed.
	(tool_cleanup): New function, copied from collect_atexit.
	(collect_atexit, handler): Just call it.
	* collect2.h (verbose): Declaration renamed from vflag.
	* lto-wrapper.c (maybe_unlink, run_gcc): Use save_temps instead of
	debug.
