[tools] Improve grokdump.py - Add new address markers: T: tagged pointer in the minidump C: address into a module in the minidump S: pointer into the exception stack in the minidump *: other address in the minidump - Show ASCII decoding of address in dd - Display potential frame markers on the exception stack: 00000032212fdae8: 0000000300000000 ........ Smi(3) EXIT frame marker - Display relative addresses, useful to detect stack frames: 00000032212fdb68: 00000032212fdb98 S ........

[bigint] Introduce BigInt type. BigInt is a new primitive type of arbitrary precision integers, proposed in https://tc39.github.io/proposal-bigint. This CL introduces a corresponding instance type, map, and C++ class to V8 and adds BigInt support to a few operations (see the test file). Much more is to come. Also, the concrete representation of BigInts is not yet fixed, currently a BigInt is simply a wrapped Smi.

[ic] Remove extra-ic-state and Map::code_cache There are only very few custom compiled IC handlers left that go in there, and for each compiled handler we only have 1 cache hit on top25; maximally saving 60ms over 33s. Additionally we'll migrate the remaining handlers to data-driven handlers anyway. Let's try to remove this code.

[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.

[Modules] Introduce ScriptOrModule and HostDefinedOptions This patch introduces a new container type ScriptOrModule which provides the name and the host defined options of the script/module. This patch also introduces a new PrimitivesArray that can hold Primitive values, which the embedder can use to store metadata. The HostDefinedOptions is passed to V8 through the ScriptOrigin, and passed back to the embedder through HostImportModuleDynamically for module loading.

[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.
