Fix the use-list-order for call and invoke instructions by setting the operands in order of their index. This matches the use-list-order prediction. Note that the verifier precludes sharing operands in callbr (so there was no bug to fix), but that code was updated for consistency. Bug was found during review of https://reviews.llvm.org/D104740. Differential Revision: https://reviews.llvm.org/D104805
