D programs broken at Language Shootout

[kmk]

I noticed the performance drop too. At closer inspection, it appears
the benchmark is taking into account those 5 programs even though they didn't run
(compilation errors due to the 'arrays not implicitly converted to pointers'
change). If you "zero" out those 5 benchmarks, D jumps up to #2.

I submitted revised versions of each of the broken programs.
