_cxa_bad_cast should be inserted by the compiler. It is called when a
dynamic_cast to a reference type fails.
_cxa_bad_typeid should be inserted by the compiler. It is called when typeid
is used on a null pointer.
_cxa_throw_bad_array_new_length should probably stay put. The most common
reason for that to get hit is if sizeof(obj) * number_of_elts > SIZE_T_MAX.
