//
// This file defines classes that make it really easy to deal with intrinsic
// functions with the isa/dyncast family of functions.  In particular, this
// allows you to do things like:
//
//     if (MemCpyInst *MCI = dyn_cast<MemCpyInst>(Inst))
//        ... MCI->getDest() ... MCI->getSource() ...
//
// All intrinsic function calls are instances of the call instruction, so these
// are all subclasses of the CallInst class.  Note that none of these classes
// has state or virtual methods, which is an important part of this gross/neat
// hack working.
