Joseph Tremoulet 0d808888c1 [WinEH] Simplify unreachable catchpads 
Summary:
At least for CoreCLR, a catchpad which immediately executes an
`unreachable` instruction indicates that the exception can never have a
matching type, and so such catchpads can be removed, and so can their
catchswitches if the catchswitch becomes empty.
