Nikolaos Papaspyrou 4ad20bff97 heap: Fix the tracing of GC cycles 
Conceptually, a full GC cycle completes when the sweeping phase is
finished. As sweeping is performed concurrently, this happens after
Heap::CollectGarbage has returned and, at the latest, before the next
full GC cycle begins. However, an arbitrary number of young GC cycles
may happen in the meantime. Tracing information for the sweeping phase
must be added to the corresponding full GC cycle event. Until now, this
was not done correctly: this information was added to the GCTracer's
current event and could thus be attributed to a subsequent young or full
GC cycle.

This CL introduces methods GCTracer::(Start|Stop)Cycle to delimit a
cycle (still allowing for full GC cycles to be interrupted by young GC
cycles). These methods are different from (Start|Stop)ObservablePause,
which delimit the observable pause of each GC. The events of "pending"
full GC cycles are kept until they are properly amended and reported,
when the sweeping phase is finished.
