[svn r86] Changed the way arguments are given storage. It is now detected if they will need it during semantic passes. Initial support for debug information. Very limited, but MUCH better than nothing :)

char[] get()
{
    return "hello";
}

void param(char[] s)
{
}

void refparam(ref char[] s)
{
}

void main()
{
    char[] dstr = get();
    param(dstr);
    refparam(dstr);
}
