When running profiling in debug mode, several assertions in frame iterators that are undoubtedly useful when iterator is started from a VM thread in a known "good" state, may fail when running over a stack of a suspended VM thread. This patch makes SafeStackFrameIterator to proactively check addresses and bail out from iteration early, before an assertion will be triggered.
