[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 interface7;

extern(C) int printf(char*,...);

interface I
{
}

class C : I
{
}

void main()
{
    I i = new C;
    ClassInfo ci = i.classinfo;
    char[] name = ci.name;
    printf("ci.name = %.*s\n", name.length, name.ptr);
    ClassInfo cI = I.classinfo;
    name = cI.name;
    printf("cI.name = %.*s\n", name.length, name.ptr);
    assert(ci is cI);
}
