`expr_simplifier` does not simplify computed `MemberExpr`s with non-literal properties

[leafypout]

Describe the feature

expr_simplifier does not simplify computed MemberExprs that have an expression as the index.

These two examples are not simplified, but both resolve to undefined:

[][[]] // undefined
[][0] // undefined

Both of these should be simplified to undefined
