bb6cc61979 fix(optional chaining): Optional delete returns true with nullish base (#10806)
Per issue 10805, the return value when using delete on a nullish base is
currently undefined. The correct return type should be true.

9c1ad0a9f7 [parser] Disallow static fields named constructor (#10461)
* Disallow static fields named `constructor` in a class

    - Disallowed static fields named `constructor` in a class (previously only non-static were disallowed)
    - Updated the text for the error for one consolidated warning, for both static and non-static fields
    - Added a test
    - Updated an existing test in the `flow` test suite of the parser to reflect the parse error.
  Strangely, the test used to pass and started failing when inlining the `isNonstaticConstructor` method, without any changes.
  In that test, `constructor` was a field, so in theory it should never have passed.
  Would appreciate some feedback on this, as I'm not 100% sure if this is somehow related to Flow

* Update test262 whitelist

* Add comment and fix && operator

The proto modifier indicates that a property declared using `x: T` syntax is actually present on the prototype object of the class, rather than an own property.
    
The proto and static modifiers are mutually exclusive, as class declarations don't simultaneously define the static prototype object, as they do the instance prototype.
    
This syntax is only supported on declared classes, not object types, interfaces, or runtime class declarations, and as such should only appear in library definitions.
