 Paolo writes: I've spent some time looking at #6042, but with not much
 success. Here's how the GHC executable size progressed with the past few
 releases:
 {{{
 7.0             31228882
 7.2             36553006
 7.4             43645088
 7.6             45291472
 head            45443324
 }}}
 Here are listings showing module sizes for 7.0, 7.2 and 7.4.  CmmParse has
 increased dramatically between 7.0 and 7.2, but then it went back down in
 later releases. There doesn't seem anything else sticking out there, it
 seems that the growth is spread mostly uniformly across modules.
 {{{

 Not sure if this is helpful, but here's a summary of the differences in
 section sizes between 7.0 and 7.2:
 {{{
 text           +2536464     14.3 %
 rodata         +1494840    151.5 %
 data           + 190880     17.9 %
 }}}
