7068240: G1: Long parallel other time and ext root scanning when running
specific benchmark
Summary: In root processing, move the scanning of the reference processor's
discovered lists to before RSet updating and scanning. When scanning the
reference processor's discovered lists, use a buffering closure so that the
time spent copying any reference object is correctly attributed. Also removed a
couple of unused and irrelevant timers.
