dyn_cast<X> - Return the argument parameter cast to the specified type.

This casting operator returns null if the argument is of the wrong type, so it can be used to test for a type as well as cast if successful. The value passed in must be present, if not, use dyn_cast_if_present. This should be used in the context of an if statement like this:

if (const Instruction *I = dyn_cast<Instruction>(myVal)) { ... }
