[PATCH] D97791: [GlobalISel] Handle non-multiples of the base type in narrowScalarInsert

[Matt Arsenault via Phabricator via llvm-commits]

arsenm added a comment.

I've been thinking we should just stop using G_INSERT/G_EXTRACT for generic legalization. They're weak abstractions over INSERT_SUBREG/EXTRACT_SUBREG, and they probably shouldn't form with illegal types/offsets.
