D compiler benchmarks

[Robert Clipsham]

Hi all,

I have set up some benchmarks for dmd, ldc and gdc at 
http://dbench.octarineparrot.com/.

There are currently only 6 tests all from 
http://shootout.alioth.debian.org/gp4/d.php. My knowledge of phobos is 
not great enough to port the others to tango (I've chosen tango as ldc 
does not support phobos currently, so it make sense to choose tango as 
all compilers support it). If you would like to contribute new tests or 
improve on the current ones let me know and I'll include them next time 
I run them.

All source code can be found at 
http://hg.octarineparrot.com/dbench/file/tip.

Let me know if you have any ideas for how I can improve the benchmarks, 
I currently plan to add compile times, size of the final executable and 
memory usage (if anyone knows an easy way to get the memory usage of a 
process in D, let me know :D).
