[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 classes5;

struct S
{
    long l;
}

class C
{
    C c;
    S s;
}

void main()
{
    C c = new C;
    long* lp = void;
    {c.s.l = 64;}
    {assert(c.s.l == 64);}
    {lp = &c.s.l;}
    {assert(*lp == 64);}
    printf("classes5 success\n");
}
