The current memory reservation approach for wasm memory tries to reserve upto the maximum, and only reserves initial if the maximum reservation fails. Add multiple retries with a smaller upper limit so that calls to grow have a higher probability of succeeding.

Currently, atomics operations are only allowed on shared memory and are enabled on regular memory behind the --wasm-atomics-on-non-shared-memory flag. Set the default value of this flag to true. This enables the following behaviors: - No validation failures when atomic opcodes are used on wasm memory backed by ArrayBuffers - memory.atomics.wait{32/64} operations will trap when wasm memory is not shared - memory.atomics.notify will always return 0 if wasm memory is not not shared.

This change enables automatic generation of Cast<> operators for classes that are defined in Torque. * Cast<> macros are generated for all classes that are defined in Torque code that are neither shapes nor marked with a new @doNotGenerateCast annotation. * Implicitly generated Cast macros simply call through to an internally-defined "DownCastForTorqueClass" macro that implements the cast using one of three strategies for efficiency. If the class has subclasses (i.e. a range of instance types including subtypes), the DownCastForTorqueClass checks for inclusion in the instance type range. If the class has a single instance type (i.e. no subclasses), then either 1) a map check is used if the class has a globally- defined map constant or 2) an equality check for the instance type is used. * Added new intrinsics to introspect class information, e.g. fetching instance type ranges for a class, accessing the globally-defined map for a class. * Removed a whole pile of existing explicit Cast<> operators that are no longer needed because of the implicitly generated Cast<> macros. * Added tests for the new Cast<> implementations.
