final.c (shorten_branches): Clear the end of the label_align array only if we made it larger.
* 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.
