The `->` operator does not have a corresponding `UnaryOperatorKind`, and so was unsupported by the `hasOperatorName` and `hasUnaryOperand` matchers. Instead of trying to determine the equivalent unary or binary operator and then deriving the opcode string, we consult `OperatorKinds.def` directly (through `getOperatorSpelling`). For `hasUnaryOperand` support, we special case the arrow operator specifically.
