[bugfix#493]

For NSException, the stack trace can be obtained through system APIs, and it is not necessary to obtain it in __cxa_throw. Therefore, this filtering is valuable and also provides some performance optimization.
But only for whether the name is an NSException as a judgment basis, still let go of some Objc exceptions. To optimize this, we suggest maintaining the list through a constant array, so far we have found _NSCoreDataException and __NSCFConstantString, and there may be more in the future;
