Fixed ModuleInfo generation to no longer use the ModuleInfo class' default initializer for types/defaults, it's unsafe as initializers don't necesarily match the "formal" type. There might be explicit padding. Changed -g switch to emit DW_LANG_D debug info, make demangling work with a patched GDB, still more work to do for full support of D's Dwarf extensions. Added getNullValue helper method.

extern(C) int printf(char*, ...);

void main()
{
     int[0][10] arr;
     printf("%u\n", &arr[9] - &arr[0]);
     int[0] arr1;
     printf("%p\n", &arr1);
     void[0] arr2;
     printf("%p\n", &arr2);
}
