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 test(T...)(T t) {
    foreach (value; t) {
        printf("%d\n", value);
        if (value == 2)
            break;
    }
}

void main() {
    test(1,4,3);
}
