More data: for PR8361 the number of functions in the .gimple dump is 5045, the
number of functions in the cleanup_cfg dump is 1341. The majority of the
functions that are eliminated are small functions, for those the extra overhead
due to inefficiencies in gimplification is significant. Maybe the people
interested in compilation speed at -O0 (especially for C++) want to take a look
at this and the related PRs...
