[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 vararg2;

void func(...)
{
    assert(_arguments.length == 2);
    assert(_arguments[0] is typeid(int));
    int a = *cast(int*)_argptr;
    _argptr += int.sizeof;
    assert(_arguments[1] is typeid(int));
    a += *cast(int*)_argptr;
    _argptr += int.sizeof;
    assert(a == 3);
}

void main()
{
    func(1,2);
}
