There's not currently a binding for this. In general, there's  
incomplete support for inspection and analysis through the C bindings.

BasicBlock::getTerminator() is just a convenient way to spell for  
dyn_cast<Terminator>(*--BB->end()). Adding bindings for isa<> would be  
the way I'd prefer to approach this, since that would be most broadly  
useful. But if your only introspection need is for  
BasicBlock::getTerminator, we could add bindings for that to be  
expedient.
