Description

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.
