[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 :/

interface MyInterface
{
    int func();
}

class MyClass : MyInterface
{
    int var;
    int func()
    {
        return var;
    }
}

void func1(MyInterface i)
{
    int delegate() dg = &i.func;
    func2(dg);
}

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

void func2(int delegate() dg)
{
    int i = dg();
    printf("%d\n", i);
}

void main()
{
    auto c = new MyClass;
    c.var = 42;
    func1(c);
}
