[wip] Codegen with memoization applied

Browse Source 
Updates the ReactiveFunction-based codegen from the previous PR to emit 
memoization code for each scope. This is currently naive and has some bugs, but 
it gets the idea across. The core logic is straightforward at this point, all 
the hard work is in earlier passes: 

* Compute one change variable per scope dependency, eg `const c_0 = $[0] === 
maxItems` 

* Generate one `let` binding for each scope output 

* Generate an if block where the test is if any of the change variables are true 
(`||` them together) 

* Generate the consequent block with the original code block, plus statements to 
save dependencies and outputs to their cache slots 

* Generate the alternate block to populate the scope outputs from their cached 
values 

## Todos 

A few things don't quite work yet: 

* Codegen is designed to avoid emitting variables for temporary values, but 
that's causing a few values to sort of disappear n the examples, or get emitted 
twice. There are a variety of ways to achieve this but we'll need to ensure that 
this category of values gets assigned to a variable and then reference the 
variable. This is more involved. 

* Scopes can end up with zero dependencies, in which case we should check that 
the first output cache is initialized. This one is more straightforward. 

* If there are early returns, we don't record that they occurred and replay them 
in the `else` branch for each scope. We know the algorithm though so i'm okay 
delaying that for now.
