eraseInstFromFunction() adds the operands of the erased instructions, as those might now be dead as well. However, this is limited to instructions with less than 8 operands. This check doesn't make a lot of sense to me. As the instruction gets removed afterwards, I don't see a potential for anything overly pathological happening here (as we can only add those operands to the worklist once). The impact on CTMark is in the noise. We also have the same code in instruction sinking and don't limit the operand count there. Differential Revision: https://reviews.llvm.org/D77325
