Detection for first-chance vs. second chance exceptions

[discostu105]

When analyzing a dump, it would be nice to know if an exception is a first-chance exception (stack not yet unwound, maybe a catch block exists) or a second chance (already unwound the stack, did not find a catch block).

Maybe a proper heuristic to find this out would be if KERNELBASE!RaiseException is on the top of the stack.
