I assume the same correlation could also be found with lines of code, but I 
think tokens is a better dimension to measure since it's less likely to be 
gamed, and it also is also kind of the basic work unit that the compiler deals 
with.

I used this patch with -fmax-tokens 1 and scraped the output for my 
measurements. I would like to avoid adding a separate flag if we can avoid it.
