André Bargull 18ae34d8f2 Improve coverage for reference type in various contexts
Missing coverage encountered while implementing
<https://github.com/tc39/ecma262/pull/3307> in SpiderMonkey.

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-*
