Failing tests:
* boostedpuncture failure likely due to code change
* GRHydro tests shows different behaviour depending on options, the
  test seems to fail only with new enough compiler, and -ffast-math
* affected hydro tests are very sensitive to data, it may be sufficient
  to use a mild increase in resolution
* as a general approach we need to decide if we want -ffast-math or if
  removing it does not affect results too much. It may be sufficient
  for gcc to specify options that allow the same subset of fast-math
  that icc uses by default
* if fast-math is needed for good performance, then we have to relax
  test constraints for these tests
* action items:
** run production benchmark with and without -fast-math on a modern
machine (Erik), use GW150914
