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.

import tango.io.Console;
void main()
{
    Cout("getting name std").newline;
    Cerr("getting name err").newline;
    auto s = Cin.get();
    Cout("putting name").newline;
    Cout (s).newline;
}
