Add a way to measure read barrier slow paths
If enabled, this option counts number of slow paths, measures the
total slow path time per GC and records the info into a histogram.
Also added support for systrace to see which threads are performing
slow paths.
Added runtime option -Xgc:measure to enable. The info is dumped
for SIGQUIT.
Test: Volantis boot with CC, test-art-host with CC, run EEAC with CC
and -Xgc:measure
