The old benchmarks measured total program run time. I ran a new
set of benchmarks, placing stopwatch calls around just the lexing
code to bypass any slowness caused by druntime startup. I also
made a similar modification to DMD.
Here's the result:

I suspect that I've made an error in the benchmarking due to how
much faster std.d.lexer is than DMD now, so I've uploaded what I
have to Github.
