Tool to simplify rewriting .mlir files. There are a couple of build in rewrites discussed below along with usage. Note: This is still in very early stage. Its so early its less a tool than a growing collection of useful functions: to use its best to do what’s needed on a brance by just hacking it (dialects registered, rewrites etc) to say help ease a rename, upstream useful utility functions, point to ease others migrating, and then bin eventually.
