Reapply "[DemandedBits] Use SetVector for Worklist"
DemandedBits currently uses a simple vector for the worklist, which means that instructions may be inserted multiple times into it. Especially in combination with the deep lattice, this may cause instructions too be recomputed very often. To avoid this, switch to a SetVector. Reapplying with a smaller number of inline elements in the SmallSetVector, to avoid running into the SmallDenseMap issue described in D56455.
