- Remove obsolete BreakLocatorType. - Perform PrepareStepOnThrow after OnException event, in case stepping was scheduled in the exception event. - Use frame count instead of frame pointer for stepping. Frame pointer is not reliable due to possible deopts. - Consistently check for inlined functions in inlined frames. - Use SharedFunctionInfo in FloodWithOneshot and EnsureDebugInfo.
