[Ryan Houdek via Phabricator via llvm-commits]

Sonicadvance1 updated this revision to Diff 138811.
Sonicadvance1 added a comment.

Addressed the comments about readability and added a unit test for the decomposing.
Had to add a specialization that uncovered an issue where vectors with only one element aren't allowed to be generated.
