[PATCH] D42092: implement C++ dr388 for the Itanium C++ ABI: proper handling of catching exceptions by reference

[John McCall via Phabricator via cfe-commits]

This is definitely something that the personality function should handle.  If we want to do heroic things in the absence of personality function support, we can, but the code should at least be written to be conditional on personality support.

If we can rev the personality function, we should also fix the longstanding problem with references to pointers to classes.
