This patch implements https://github.com/tc39/proposal-class-fields/pull/269 and makes sure we always throw TypeError when there is invalid private name access in computed property keys. Before this patch, private name variables of private fields and methods are initialized together with computed property keys in the order they are declared. Accessing undefined private names in the computed property keys thus fail silently. After this patch, we initialize the private name variables of private fields before we initialize the computed property keys, so that invalid access to private fields in the computed keys can be checked in the IC. We now also initialize the brand early, so that invalid access to private methods or accessors in the computed keys throw TypeError during brand checks - and since these accesses are guarded by brand checks, we can create the private methods and accessors after the class is defined, and merge the home object setting with the creation of the closures.

This patch implements the access of private accessors by loading the referenced component from the AccessorPair associated with private name variables. It also makes the error messages for invalid kind of private accessor access more specific.

This patch implements the declaration of private accessors. When iterating over the class properties, we track private accessors associated with the same name in a ZoneHashMap. Once we get to all the necessary components for a private name (we know statically whether we should expect only a setter, only a getter, or both), we emit a call to a runtime function `CreatePrivateAccessors` that creates an AccessorPair, and store the components in it. The AccessorPair is then associated with the private name variable and stored in the context for later retrieval when the private accessors are accessed.

This patch adds: - VariableMode::kPrivateMethod - VariableMode::kPrivateSetterOnly - VariableMode::kPrivateGetterOnly - VariableMode::kPrivateGetterAndSetter And replace the previous RequiresBrandCheckFlag by inferring whether the brand check is required from these VariableModes. It is then possible to check duplicate non-complementary accessors in the parsers and throw early errors, and allow complementary accessors to be associated with the same private name variable. This patch also adds the following AssignType: - PRIVATE_METHOD - PRIVATE_GETTER_ONLY - PRIVATE_SETTER_ONLY - PRIVATE_GETTER_AND_SETTER corresponding to the new VariableModes so that it's possible to generate specialized code for different type of private accessor declarations.
