[PATCH] [WinEH] Update C++ exception state numbering code

[Andy Kaylor]

Hi majnemer, rnk,

This patch updates the code that calculates C++ exception states.  The results after this patch still have some problems, but it is much better.  In particular, this patch helps with rethrowing exceptions from within a catch handler.
