Subject: Ch10update (#75)

* Store-after-Store peep

* Load-after-Store peephole

* Fix graph viz mem edge color bug

* Scalar replace loop carried dependence

* #67 Dead Not node hanging around - if we add a Not in the upcast then add it to the IterPeeps worklist to ensure it gets cleaned up. We don't see the Not node in the parser hence we cannot do a peep on it there.

* #67 Update visuals. Add description of Store-Store and Store-Load peeps. Add examples.

* #67 Undo the change that wasn't supposed to be committed!

* #67 Update description of the Store-Store and Store-Load peepholes
