Comment:

 As perhaps expected, the above commit sped up the build by 20 seconds:
 https://perf.haskell.org/ghc/#revision/9304df5230a7a29d3e992916d133e462b854e55f
 (click the "=" at the top right to see the build time) which means that
 we've accounted for the regressions from the top-level strings patch.
