Luke Wilde 3a48c7fdaf LibJS/Bytecode: Check for lexical bindings only in current scope ...

BlockDeclarationInstantiation takes as input the new lexical
environment that was created and checks if there is a binding for the
current name only in this new scope.

This allows shadowing lexical variables and prevents us crashing due to
an already initialized lexical variable in this case:
```js
let x = 1;
{
    let x = 1;
}
```
