[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 typeinfo13;

void main()
{
    float[long] aa;
    auto ti = typeid(typeof(aa));
    assert(ti.toString() == "float[long]");
    assert(ti.next() is typeid(float));
    assert(ti.tsize() == size_t.sizeof);
    auto aati = cast(TypeInfo_AssociativeArray)ti;
    assert(aati.value is typeid(float));
    assert(aati.key is typeid(long));
}
