6898948: G1: forensic instrumentation for out-of-bounds recent_avg_pause_time_ratio()
Summary: Added instrumentation and (temporary) assert in non-product mode; clipped the value when found out-of-bounds in product mode. Fix of original issue will follow collection of data from this instrumentation.
