phobos src level stats

[Bruce Carneal]

Below you'll find category line percentages and total line counts 
for the 20 biggest files in phobos.

The "line" counts following the file names are of the 
dscanner/libdparse variety rather than the 'wc' variety.

On a 2.4GhZ zen1, libdparse managed all of phobos in a little 
under 1.5 seconds.  For comparison note that all files were read 
in a little under 10 milliseconds (from file cache).

I really enjoyed my first interaction with libdparse but I'm 
guessing that the maintainers there strongly favor 
clarity/correctness over speed.  One other note, compiling with 
dub's --combined option cut the execution time of the 
ldc2/release exe by about 2X.
