[PATCH] D107650: GlobalISel[RFC]: Avoid use of G_INSERT and G_EXTRACT in Legalizer

[Petar Avramovic via Phabricator via llvm-commits]

Petar.Avramovic updated this revision to Diff 366880.
Petar.Avramovic added a comment.

Use unmerge/build_vector instead of new artifacts.

This requires more work during combine since we need to check if unmerged elements are not merged in shuffled order for a simple copy.
