[PATCH] D79567: [GlobalISel] Combine scalar unmerge(trunc)

[Dominik Montada via Phabricator via llvm-commits]

gargaroff added a comment.

Not sure whether this combine is desired. We need it for our out-of-tree backend, as otherwise there are quite a few cases with non-power-of-2 types which fail legalization due to non-combinable unmerge(trunc(merge)) patterns.
