Comment (by Ben Gamari ):

 In [changeset:"d11611f5739284cc6aab9b2636ac6485352107ea/ghc" d11611f/ghc]:

 Add NOINLINE pragma to builtinRules

 As mentioned in #14275, GHC will otherwise decide to produce unfoldings
 for this rather large binding, making recompilation more expensive than
 necessary. Since inlining is almost certainly not fruitful mark it as
 NOINLINE.
