[Bug] Handle separated declaration and assignment

[Semnodime]

var foo;
foo = [42];
console.log(foo[0]);

should be handled identically with

var foo = [42];
console.log(foo[0]);

and be deobfuscated to

console.log(42);

It's a little more complicated to handle these cases, but yes would be nice to have.
