 While browsing the nofib results comparing 7.6.1 and HEAD today, I noticed
 that binary sizes for `grep` are significantly larger in HEAD:

 {{{
 grep
            Main                34706          +31.3%
         Parsers                 5791           +3.2%
     StringMatch                28227          +36.9%
 }}}

 The increase seems to be happening in the simplifier, going by the code-
 size stats generated by `-v`.  This probably warrants investigation before
 7.8.1.

 Binary sizes are slightly larger across the board (1-2%), which is at
 least partly due to the new code generator, however performance is
 slightly better (2-3%), if these numbers are to be believed.
