[Attributor][FIX] Do not attach range metadata to the wrong Instruction

If we are looking at a call site argument it might be a load or call
which is in a different context than the call site argument. We cannot
simply use the call site argument range for the call or load.

Bug reported and reduced by Whitney Tsang <whitneyt@ca.ibm.com>.
