Preliminary testing shows a 37% speedup when compiling the compiler with
  itself.  tak20 shows a 70% speedup.  This is most likely due to the
  CPU doing a better job of branch prediction.

Note: this relies on a gcc extension that many compilers also
  support. In previous releases of Xcode, this extension was disabled by
  default, but this seems to no longer be the case (mar 2017).
