[mlir] NFC: fix trivial typos

[kiszk]

Summary

fix typo under include and lib directories

[herhut]

Thanks for fixing these. Just some remarks while looking through the changes.

mlir/lib/Dialect/Linalg/Transforms/Fusion.cpp

772

While at it, this could be a two line string.

mlir/lib/Dialect/StandardOps/IR/Ops.cpp

1464

This elides the .

mlir/lib/Dialect/StandardOps/Transforms/ExpandOps.cpp

1

Also drop the 0 from 0to?

[kiszk]

Thank you for your comments. I addressed the comments.
