Add no-op NULL picture to bench_record.

Browse Source 
Defaults of out/Release/bench_record are still fine; NULL's not too far off
from stable at 900 loops.  But for focus on NULL, I'd recommend
something like out/Release/bench_record --loops 100000 --skps.

Also: fail on failures, print 2 significant digits instead of fixed 4.2.
