Bjorn Pettersson fecef6be9e [LoopVersioning] Don't modify the list that we iterate over in addPHINodes ... Summary: In LoopVersioning::addPHINodes we need to iterate over all users for a value "Inst", and if the user is outside of the VersionedLoop we should replace the use of "Inst" by using the value "PN" instead. Replacing the use of "Inst" for a user of "Inst" also means that Inst->users() is modified. So it is not safe to do the replace while iterating over Inst->users() as we used to do. This patch splits the task into two steps. First we iterate over Inst->users() to find all users that should be updated. Those users are saved into a local data structure on the stack. And then, in the second step, we do the actual updates. This time iterating over the local data structure.
