sorry, I couldn't find anything about `emitMatchFailure` [[Link](https://www.google.com/search?sca_esv=575897283&q=mlir+%22emitMatchFailure%22&sa=X&ved=2ahUKEwjN79Kxk42CAxXoMjQIHXWiAt4Q5t4CegQIExAB&biw=1844&bih=866&dpr=2)]. When I tried to build it, it also fails. Other passes are also using `signalPassFailure()`
