[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 bug13;

void func1(ubyte[4]* arr)
{
    ubyte* b = &(*arr)[0];
    func2(&(*arr)[1]);
}

void func2(ubyte* ptr)
{
    assert(*ptr == 2);
}

void main()
{
    ubyte[4] arr = [cast(ubyte)1,2,3,4];
    func1(&arr);
}
