Depending on the kind of casts in the source code, `CStyleCastExpr` or
`CXXReinterpretCastExpr` (or possibly another cast kind) is used when casting
to a completely different function pointer type.
But those are explicit casts. I'm not sure there's another cast operation other
than `CK_NoOp` in `clang/AST/OperationKinds.def` that we can use for that
purpose.
