Change tupledesc->attrs[n] to TupleDescAttr(tupledesc, n).

Browse Source 
This is a mechanical change in preparation for a later commit that
will change the layout of TupleDesc.  Introducing a macro to abstract
the details of where attributes are stored will allow us to change
that in separate step and revise it in future.
