We introduce a new pass, which focuses on simplifying bitwise operations against constant masks; when splits are enabled, these can be transformed into concats of BitSlices and Literals. This is mostly useful when the user has written a software-optimized bit-twiddling routine. PiperOrigin-RevId: 978271862
