This CL makes the ScriptContextTable concurrently accessible from the background thread (in particular ScriptContextTable::get_context). A cctest is added to check synchronization with tsan.

This changes how we setup modules from being entirely bytecode based to a single fixed array with metadata that's passed into a runtime function DeclareModuleExports, similar to DeclareGlobals. This is preperatory work to replace the bytecode that calls those functions with explicit calls before we even start running the code. In the case of modules that will obviate the need for modules to be generators.

This CL factors out the decision-making logic whether a property key should be treated as a "property" or "element" into LookupIterator::Key, which can be constructed on its own, allowing use sites to take this distinction into account before constructing a LookupIterator from the Key, without needing to duplicate the logic. This also makes the assortment of LookupIterator constructors more uniform.

Design doc: bit.ly/v8-repl-mode This CL adds a new REPL mode that can be used via DebugEvaluate::GlobalREPL. REPL mode only implements re-declaration of 'let' bindings at the moment. Example: REPL Input 1: let x = 21; REPL Input 2: let x = 42; This would normally throw a SyntaxError, but works in REPL mode. The implementation is done by: - Setting a 'repl mode' bit on {Script}, {ScopeInfo}, {ParseInfo} and script {Scope}. - Each global let declaration still gets a slot reserved in the respective {ScriptContext}. - When a new REPL mode {ScriptContext} is created, name clashes for let bindings are not reported as errors. - Declarations, loads and stores for global let in REPL mode are now "load/store global" instead of accessing their respective context slot directly. This causes a lookup in the ScriptContextTable where the found slot for each name is guaranteed to be the same (the first one).

A window is a Blink concept. This API marks the context as backing a detached window. This doesn't necessarily mean that the context is detached. Every time a JS function is called within a context that has a non-zero DetachedWindowReason, Runtime::kReportDetachedWindowAccess is invoked, which will report this call to Blink via a callback, which in turn can report number of such calls via UKM metrics.

When global object has proxies we should first call hasProperty and then call GetProperty according to spec. This cl fixes both LoadGlobal and LoadLookupGlobal to correctly handle these cases. Also fixes tests that didn't expect hasProperty to be called.

Context objects have an extension slot, which contains further additional data that depends on the type of the context. This CL removes the extension slot from contexts that don't need them, hence reducing memory. The following contexts will still have an extension slot: native, module, await, block and with contexts. See objects/contexts.h for what the slot is used for. The following contexts will not have an extension slot anymore (they were not used before): script, catch and builtin contexts. Eval and function contexts only have the extension slot if they contain a sloppy eval.

This patch uses a bit in the Variable bit fields to distinguish static private names from instance private names, so that we can check the conflicts of private accessors that are complementary but with different staticness in the parser, and use this information later when generating code for checking static brands for private method access.

This CL changes how variables are resolved during debug evaluate. We now re-parse the whole script when creating a ScopeIterator. This gives us accurate scope information for all parent scopes of the closure in which we stopped. Using this information, we build blacklists of stack-allocated variables. Each context on the chain in between the closure context up to the original native context is wrapped in a debug-evaluate context with such a blacklist attached. Variable lookup for debug-evalute contexts then works as follows: 1) Look up in the materialized stack variables (stayed the same). 2) Check the blacklist to find out whether to abort further lookup. 3) Look up in the original context. Steps 1-3 is repeated for each debug-evaluate context, since they mirror the original context chain.

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.

Introduce SourceTextModule as a subclass of Module. Move all the JavaScript-module-specific code down from Module to SourceTextModule, with all code applicable to other future module types remaining in Module. With this change, Module is roughly equivalent to the spec's Abstract Module Record and SourceTextModule is roughly equivalent to Source Text Module Record.

This patch adds a new assign type `PRIVATE_METHOD`. We now use this for private method references in the form `obj.#key` when `#key` resolves to a private method. To obtain the type of the key variables after scope analysis, this patch add a bit to Variable to recognize private method variables whose load requires a brand check. Also renamed `PropertyExpressionWithPrivateFieldKey` in ExpressionType to `PrivateReference` and added `PRIVATE_CALL` to `CallType` - we'll use the new types later when we implement private methods, which require special brand checking semantics to load methods directly from the context instead of from the object in order to save memory.
