/**
* mono_arch_get_throw_corlib_exception:
*
* Returns a function pointer which can be used to raise
* corlib exceptions. The returned function has the following
* signature: void (*func) (guint32 ex_token, guint32 offset);
* Here, offset is the offset which needs to be substracted from the caller IP
* to get the IP of the throw. Passing the offset has the advantage that it
* needs no relocations in the caller.
