A landing pad can be jumped to only by the unwind edge of an invoke instruction. If we eliminate a partially redundant load in a landing pad, it will create a basic block that violates this constraint. It then leads to other problems down the line if it tries to merge that basic block with the landing pad. Avoid this by not eliminating the load in a landing pad.
