Partially undo commit 94da73281. On closer inspection, mcv.c isn't as broken for ScalarArrayOpExpr as I thought. The Var-on-right issue is real enough, but actually it does cope fine with a NULL array constant --- I was misled by an XXX comment suggesting it didn't. Undo that part of the code change, and replace the XXX comment with something less misleading.
