[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 interface1;

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

interface Inter
{
    void func();
}

class Class : Inter
{
    override void func()
    {
        printf("hello world\n");
    }
}

void main()
{
    scope c = new Class;
    c.func();
    Inter i = c;
    i.func();
}
