As discussed in http://lists.llvm.org/pipermail/llvm-dev/2020-July/143801.html. Currently no users outside of unit tests. Replace all instances in tests of -constprop with -instsimplify. Notable changes in tests: * vscale.ll - @llvm.sadd.sat.nxv16i8 is evaluated by instsimplify, use a fake intrinsic instead * InsertElement.ll - insertelement undef is removed by instsimplify in @insertelement_undef llvm/test/Transforms/ConstProp moved to llvm/test/Transforms/InstSimplify/ConstProp Reviewed By: lattner, nikic Differential Revision: https://reviews.llvm.org/D85159
