[PATCH] D87936: [GISel] Add new combines for G_ADD

[Michael Kitzan via Phabricator via llvm-commits]

mkitzan updated this revision to Diff 430529.

Good point about using `mi_match`, updated the diff.

Can work on the add -> or combine + helper function in a future patch. Better to not block committing the simpler combines.
