Fixes #104505 I was originally going to ban all usages of as_strided + mutation in functionalization. But I'm pretty sure that as_strided + mutation is fine when we are calling as_strided on a base tensor. So in this PR I added a slightly more conservative check: if we see an as_strided + mutation, where the input to an as_strided was **another** view op, then I error loudly in functionalization and link to the github issue above (in case anyone runs into this in the real world) cc voznesenskym penguinwu EikanWang jgong5 Guobing-Chen XiaobingSuper zhuhaozhe blzheng wenzhe-nrv jiayisunx chenyang78 kadeng chauhang [ghstack-poisoned]
