Joe Savona ef34ca6cb0 Model other assignment variants as values ...

The previous PR only updated simple assignment expressions (where the lvalue is 
an identifier), this PR extends the same idea to all assignment variants. Note 
that there is one case that doesn't work yet, which is complex destructuring 
assignment as a value: 

```javascript 

let x = makeObject(); 

x.foo(([[x]] = makeObject())); 

``` 

What happens here is that we lower the destructuring to a series of steps: 

``` 

tmp1: Destructure Const [ tmp0 ]  = makeObject(); 

tmp2: Destructure Reassign [ x ] = tmp0; 

PropertyCall x, 'foo', [ tmp1 ] 

``` 

Thankfully we can detect this case: if we have a const/let declaration with an 
lvalue, that's invalid. See the new error test case which shows we correctly 
detect & reject this case for now.
