◆ replaceIfSimplePointerUse()
If OldV is used as the pointer operand of a compatible memory operation Inst, replaces the pointer operand with NewV.
This covers memory instructions with a single pointer operand that can have its address space changed by simply mutating the use to a new value.
returns true the user replacement was made.
