Reduce statistical heap sampling memory overhead. If the mean heap sampling interval is larger than one page, simulate sampled small objects with large objects. This allows profiling context pointers to be omitted for small objects. As a result, the memory overhead for sampling decreases as the sampling interval is increased. Fix a compilation error in the profiling code.
