Hit an assertion in `ignoreOp` when testing the refactored code.

```
Assertion failed: (OpIdx < I->getNumOperands() && "Invalid operand index"), function ignoreOp, file GlobalMergeFunctions.cpp, line 129.
Stop reason: hit program assert
expr I->dump()
  %6 = tail call ptr @objc_retain(ptr %5), !dbg !576

p I->getNumOperands()

(unsigned int) 2
p OpIdx
