make SIGUSR2 dump and reset stats
Make resetting time work
base/statistics.cc:
Fix statistics reset so that it works again, and correctly
reset bins as well. (The old code wouldn't reset if you didn't
have any bins, and then would actually only reset the first
bin)
cpu/simple_cpu/simple_cpu.cc:
cpu/simple_cpu/simple_cpu.hh:
convert idleCycles/idleFraction into a single Average stat
to make reset work more simply
sim/main.cc:
handle SIGUSR2 to dump and reset stats
(SIGUSR1 only dumps them)
sim/sim_time.cc:
sim/sim_time.hh:
Add support for resetting the time
