Clean up build warnings about redundant constraints when built with ghc 8.0.
Only a couple of the constraints were really redundant. The rest are
essential to propellor's tracking of Info propigation, so I silenced the
warning for those.
It would be better to only silence the warning for the functions with the
extra constraints, but IIRC warnings can only be silenced on an entire file
basis.
