Comment(by pcapriotti):
Here are some timings:
ghc-6.12.3: 287 ms
ghc-7.0.4: 316 ms
ghc-7.2.1: 269 ms
ghc-7.4.2: 265 ms
ghc-HEAD: 267 ms
It appears that the regression has been fixed sometime before 7.2.
Before we close the ticket, should we remove the test case which checks
whether `rnf` is inlined?
