We usually don't change the name of structs between the struct name itself and the name of the typedef. Additionally, structs that are usually used via a typedef that hides being a pointer, are commonly suffixed Data. Change tupdesc code to follow those convention. This is triggered by a future patch that intends to forward declare TupleDescData in another header - keeping with the naming scheme makes that easier to understand.
