[svn r229] Updated the object.d implementation to the latest Tango. Fixed a bunch of the built-in typeinfos for arrays, they did not inherit TypeInfo_Array. Applied patch to tango/text/convert/Layout.d by fvbommel, closes #47 . Cleaned up some type code. Replaced uses of llvm::Type with LLType (a typedef), same for Value and Constant. Fixed a few cases where typeinfo for user structs could be emitted multiple times, seems to still be some cases of this :/

module nested7;

void main()
{
    int i;
    i = 52;
    printf("i = %d\n", i);

    void func()
    {
        i++;

        void func2()
        {
            i++;

            void func3()
            {
                i++;
            }

            func3();
        }

        func2();
    }

    func();

    printf("i = %d\n", i);
    assert(i == 55);
}
