  -----------
  [mlir][sparse] refine absent branch feeding into custom op

Document better that unary/binary may only feed to the output
or the input of a custom reduction (not even a regular reduction
since it may have "no value"!). Also fixes a bug when present
branch is empty and feeds into custom reduction.
