The "each" slot is only actually used by ForIn, so this simply cleans up a TODO of mine and removes an IsForOfStatement() call. Review URL: https://codereview.chromium.org/1742013002 Cr-Commit-Position: refs/heads/master@{#34369}

Rename the existing (patching) ToBooleanStub to ToBooleanICStub to match our naming convention, and add a new TurboFan-powered ToBooleanStub, which just does the ToBoolean conversion without any runtime call or code patching, so we can use it for Ignition (and TurboFan). Drive-by-fix: Add an Oddball::to_boolean field similar to the ones we already have for to_string and to_number, so we don't need to actually dispatch on the concrete Oddball at all.

port 55b4df73(r34303) original commit message: Only use one set of %StrictEquals/%StrictNotEquals and %Equals/%NotEquals runtime entries for both the interpreter and the old-style CompareICStub.

Since both null and undefined are also marked as undetectable now, we can just test that bit instead of having the CompareNilIC try to collect feedback to speed up the general case (without the undetectable bit being used). Drive-by-fix: Update the type system to match the new handling of undetectable in the runtime.

Port d00da47b Original commit message: The CompareICStub produces an untagged raw word value, which has to be translated to true or false manually in the TurboFan code. But for lazy bailout after the CompareIC, we immediately go back to fullcodegen or Ignition with the raw value, to a location where both fullcodegen and Ignition expect a boolean value, which might crash or in the worst case (depending on the exact computation inside the CompareIC) could lead to arbitrary memory access. Short-term fix is to use the proper runtime functions (unified with the interpreter now) for comparisons. Next task is to provide optimized versions of these based on the CodeStubAssembler, which can then be used via code stubs in TurboFan or directly in handlers in the interpreter.

Reland of Make Intl install properties more like how other builtins do (patchset #1 id:1 of https://codereview.chromium.org/1733293003/ ) This reland fixes a bug by pulling properties off the utils object, so that it can be garbage collected in nosnap builds. Original commit message: Intl has been somewhat of an oddball for how it integrates with V8. One aspect is that it largely didn't use utils to install itself into the snapshot, which led to some missing names, which new test262 tests check for, and duplicated code. This patch brings Intl a bit closer to how the rest of the builtins do things, though not entirely as it is currently structured to do unusual things, such as creating new constructors from JavaScript rather than C++. New test262 tests check for some of the names that are added in this patch.

Port 3ef573e9 Original commit message: Replace the somewhat awkward RestParamAccessStub, which would always call into the runtime anyway with a proper FastNewRestParameterStub, which is basically based on the code that was already there for strict arguments object materialization. But for rest parameters we could optimize even further (leading to 8-10x improvements for functions with rest parameters), by fixing the internal formal parameter count: Every SharedFunctionInfo has a formal_parameter_count field, which specifies the number of formal parameters, and is used to decide whether we need to create an arguments adaptor frame when calling a function (i.e. if there's a mismatch between the actual and expected parameters). Previously the formal_parameter_count included the rest parameter, which was sort of unfortunate, as that meant that calling a function with only the non-rest parameters still required an arguments adaptor (plus some other oddities). Now with this CL we fix, so that we do no longer include the rest parameter in that count. Thereby checking for rest parameters is very efficient, as we only need to check whether there is an arguments adaptor frame, and if not create an empty array, otherwise check whether the arguments adaptor frame has more parameters than specified by the formal_parameter_count. The FastNewRestParameterStub is written in a way that it can be directly used by Ignition as well, and with some tweaks to the TurboFan backends and the CodeStubAssembler, we should be able to rewrite it as TurboFanCodeStub in the near future. Drive-by-fix: Refactor and unify the CreateArgumentsType which was different in TurboFan and Ignition; now we have a single enum class which is used in both TurboFan and Ignition.

This patch adds the newly added support for contexts in V8 Tracing, as well as use it to mark all the entry points for a V8 Isolate. Update for reland: The current tracing interface needs to be updated (AddTraceEvent), but the embedders need to migrate to the new version before removing the old version. (Reland of: https://codereview.chromium.org/1686233002) The revert happened because the 2 signatures of the old and new AddTraceEvent where different so it threw an overload-virtual error on cross arm debug. This issue is temporary, and to solve it, I added an implementation of the old and new everywhere until the embedder implements the new.

Port ba2077aa Original commit message: Move the already existing fast case for %NewObject into a dedicated FastNewObjectStub that we can utilize in places where we would otherwise fallback to %NewObject immediately, which is rather expensive. Also use FastNewObjectStub as the generic implementation of JSCreate, which should make constructor inlining based on SharedFunctionInfo (w/o specializing to a concrete closure) viable soon.
