After the MemRef has been split out of the Standard dialect, the conversion to the LLVM dialect remained as a huge monolithic pass. This is undesirable for the same complexity management reasons as having a huge Standard dialect itself, and is even more confusing given the existence of a separate dialect. Extract the conversion of the MemRef dialect operations to LLVM into a separate library and a separate conversion pass.
