It is illegal to merge two `llvm.coro.save` calls unless their `llvm.coro.suspend` users are also merged. Marks it "nomerge" for the moment. This reverts D129025. Alternative to D129025, which affects other token type users like WinEH. Reviewed By: ChuanqiXu Differential Revision: https://reviews.llvm.org/D129530
