* final.c (shorten_branches): Clear the end of the label_align

	array only if we made it larger.  Break up messy expressions
	for clarity.

	* diagnostic.c (internal_error): Check for error recursion
	before doing ICE suppression.

	* timevar.c: Timing variables now count in milliseconds.
	(init_timevar): Set up ticks_to_msec and clocks_to_msec here.
	(get_time): Not here.
	(timevar_print): Don't print any timer whose user, cpu, and
	wall times are all zero as displayed.
	* timevar.h: Update comment aboout units.  Make timevar
	counters unsigned.
