This is the same diff as https://reviews.llvm.org/D88809/ except side effect free check is removed for involution and a FIXME is added until the dependency is resolved for shared builds. The old diff has more details on possible fixes. Reviewed By: rriddle, andyly Differential Revision: https://reviews.llvm.org/D89333
