Don't assume that __cxa_current_exception_type exists.
Normally you shouldn't be able to have a process with an ItaniumABI plugin
that doesn't have this symbol. But if the loader crashes before loading
libc++abi.dylib (on MacOS), then the symbol might not be present. So we
should check before accessing the pointer.
There isn't a good way to write a test for this, but the change is obvious.
