 Summary from the commit message:

 {{{
 Enable -funbox-small-strict-fields by default

 The flag shows no real impact on nofib benchmarks and GHC itself,
 which is expected given the small number of strict but not already
 unpacked fields in the source of these programs. However, the flag
 allows us to omit most of the UNPACK pragmas that are so common in
 source code today.
