This patch removes handling of references to unset objects that relied
on Original_Node. This handling was only needed because of rewriting
that reused operator nodes, for example, when an array inequality like:
A < B
was rewritten into:
System.Compare_Array_Unsigned_8.Compare_Array_U8
(A'Address, B'Address, A'Length, B'Length) < 0
by keeping the node for operator "<" and only substituting its operands.
It seems safer to simply create an new operator node when rewriting and
not rely on Original_Node afterwards.
Cleanup related to improved detection uninitialized objects.

* checks.adb (Apply_Arithmetic_Overflow_Strict): Rewrite using a
newly created operator node.
* exp_ch4.adb (Expand_Array_Comparison): Likewise.
* exp_ch6.adb (Add_Call_By_Copy_Code): Rewriting actual parameter
using its own location and not the location of the subprogram
call.
* sem_warn.adb (Check_References): Looping with Original_Node is
no longer needed.
