Reduce max instance type enum value. We collect instance type statistics in FatalProcessOutOfMemory into an array, which is allocated to the max instance type value. While we want to leave space to ensure new instance types do not affect constants in the API, we can be more frugal. We currently serialize 350 maps into the startup/context snapshot. Even if we assign a distinct instance type to each of these maps, we would still have more than enough to spare with this change.

[cleanup] Unify enum cache handling. Introduce a proper empty_descriptor_array, which has the proper layout (length is 2 and the two fields are set properly). Also add a special EnumCache class and a matching empty_enum_cache. The contract now is that we only need to check the EnumLength on the map to know whether we are allowed to use the enum cache. This greatly simplifies the handling of the enum cache (and also the descriptor arrays), especially for the future work on optimizing keyed access via the enum cache indices.

[snapshot] no longer iterate strong roots twice. Previously, in order to get immortal immovable objects onto the first page, the serializer would iterate the root list twice. The first time it would prioritize immortal immovables. The second time it would serialize the rest. This does not guarantee that immortal immovable objects actually end up on the first page, and by now this is not necessary anymore, since we mark all pages created during heap init as immortal immovable pages.

[turbofan] Reduce promise creation overhead in async functions This adds a new operator JSCreatePromise, which currently allocates a native JSPromise instance and initializes it to pending state. In addition to that we introduce a new PromiseHookProtector, which get's invalidated the first time someone enables the debugger or installs a PromiseHook (via async_hooks for example). As long as the protector is intact we lower AsyncFunctionPromiseCreate to JSCreatePromise and AsyncFunctionPromiseRelease to a no-op in optimized code. This yields a speedup of roughly 33% on the benchmark mentioned in the bug.

[wasm] [debug] Implement calling imported wasm functions The interpreter was not able to call imported wasm functions (hitting UNIMPLEMENTED). This CL fixes this by creating a "CWasmEntry", which is signature-specific. It has JS linkage and receives the wasm code object to call and a buffer containing all arguments (similar to the interpreter entry). It loads all arguments from the buffer and calls the given code object. The c-wasm-entry code objects are cached per instance, such that we only create them once per signature. These wasm entry stubs will also allow us to call back to compiled code from the interpreter, which we might want to do to reduce the slowdown of executing wasm for debugging.

Inline Array.prototype.forEach in TurboFan This CL contains a few pieces: - A new mechanism to create "BuiltinContinuation" checkpoints in TurboFan graphs, which--when triggered--swizzle the values in the the FrameState to be parameters to a typically TF-generated builtin that resumes execution to finish the slow-case functionality. - Continuation builtins that have special handling in the deoptimizer and their own new frame type to ensure that the values they need to begin executing can be stashed away and restored immediately before the builtin is called via a trampoline that runs when the continuation builtin's frame execution resumes. - An implementation of Array.prototype.forEach in TurboFan that can be used to inline it. The inlined forEach implementation uses the checkpoints mechanism described above to deopt in the middle of the forEach in the cases that optimization invariants are violated. There is a slightly different continuation stub for each deopt point in the forEach implementation to ensure the correct side-effects, i.e. that the deopt of the builtin isn't programmatically observable.

[cpu-profiler] Introduce NativeFrame type. The new frame type is inteneded to represent native C++ stack frames. JS code may sometimes make calls to helper native functions that do not provide any special stack layout besides the return address and frame pointer. Currently the stack iterator bails out when it sees an unknown frame. The patch allows the iterator to unwind stacks having such frames.
