10/// This pass converts vector operations into scalar operations (or, optionally,
11/// operations on smaller vector widths), in order to expose optimization
12/// opportunities on the individual scalar operations.
13/// It is mainly intended for targets that do not have vector units, but it
14/// may also be useful for revectorizing code to different vector widths.
