[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 multiarr1;

void main()
{
    int[16][16] a;
    a[10][13] = 42;
    //assert(a[0][0] == 0);
    //assert(a[10][13] == 42);
    {
        int* l = cast(int*)a;
        l += 10*16+13;
        assert(*l == 42);
    }
}
