Check known-key lists
I noticed that fmap (for example) has a known key
fmapName = varQual gHC_BASE (fsLit "fmap") fmapClassOpKey
fmapClassOpKey = mkPreludeMiscIdUnique 173
but its RdrName doesn't refer to it.
fmap_RDR = varQual_RDR gHC_BASE (fsLit "fmap")
Is there a reason for this? If not, it seems likely that we could get a bit of a speed-up by using fmapName here. We may also consider making liftA2 known-key for Traversable deriving.
