Ensure environment lookups are performed in the correct order:
- keyed-destructuring-property-reference-target-evaluation-order-with-bindings.js
Ensure `delete super[elem]` steps are correctly performed:
- delete/super-property-topropertykey.js
- delete/super-property-uninitialized-this.js
Ensure ToPropertyKey for computed property names in object literals
correctly performed:
- object/computed-property-name-topropertykey-before-value-evaluation.js
Ensure `GetSuperBase` is executed before `ToPropertKey`:
- super/prop-expr-getsuperbase-before-topropertykey-*
Ensure `GetThisBinding` is executed first:
- super/prop-expr-uninitialized-this-*
