George Hotz d1cce7a476 put the ranges on store instead of after (#15759)
* put the ranges on store instead of after

* better assert

* fix stuff

* comment out slow rules i don't understand

* simpler rule

* closer

* return false for store

* fix loop

* only a few schedule failures remain

* remove stores to self

* all tests pass locally

* remove junk

* regression test and fix

* better test, bump broken torch count

* bugfix with regression test

* new fusion is better
