Thanks. These patterns aren't only used by MLIRArithToLLVM: the arith-expand pass (populateArithExpandOpsPatterns) and the SPIR-V test pass use them too, so moving them into ArithToLLVM would make MLIRArithTransforms depend on a conversion library. (@RoboTux suggested ArithUtils in #117305 for this reason.)

An alternative is to create another library for these patterns.
