`getStaticValue` doesn't track references types correctly

[RunDevelopment]

Example: const a = []; a === a will evaluate to false.

This is because getStaticValue evaluates each reference to a variable separately, so we get different objects with the same value each time. However, they should be the same value.

Solution: Cache the value of each variable.

Non-solution: Change the === operator (among others) to not evaluate the equality of non-value types. This solution simply doesn't scale as built-in safe functions might use === under the hood.
