[mlir] factor memref-to-llvm lowering out of std-to-llvm

[ftynse]

Summary

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.

A big change, so you probably want people from all over to review. I looked at the vector and sparse changes, and they LGTM.
Thanks for doing this refactoring, that must have been a bit of a pain ;-)

[ftynse]

The change is pretty mechanical, mostly moving code around and making sure the new pass is called whenever relevant. I don't expect a deep review here.

Yeah, I mostly meant getting a review from all the many different component owners, not necessarily a very deep one.

Thanks for doing this! I did not deeply review all the tests and code, as I assume it was mostly copied/moved. Please fix the few minor things I found.

It seems to be a common theme but why are all the passes module passes here? Is there a technical reason?

No need to change it as part of this refactoring.

This is missing the comment header.

Nit: Extra space.

Debugging left-over?

Is this useful?

I don't know about the other passes, memref-to-llvm needs to be a module pass because it rewrites memref.global operations are module-level symbols. Function pass wouldn't even see those because they are outside of functions, and there are also concurrency concerns.
