This adapts the predicate in question to be geared towards TurboFan now that Crankshaft is no longer being used. It makes the predicate respect the --allocation-site-pretenuring flag again in all cases.

AllocationSite objects survive if a page moves within new space. The intended behavior was to update the count only when they are visited by the Scavenger the first time, as they would die afterwards. This fixes that case where we would move a page within new space where most objects survive. We would unnecessarily update the AllocationSite in this case.

This makes sure that the coercion of global import values to numbers remains non-observable to JavaScript. It allows instantiation failures to fall back to JavaScript proper without accidentally causing some side-effect to happen twice. Also coercions might invalidate previous checks done during linking or throw exceptions.

This was never legal; the spec only allows '\0' in strict-mode strings or templates when not followed by a decimal digit. Previously we were only enforcing that it not be followed by an _octal_ digit. This was already fixed for numeric literals, but not for escape sequences in strings.

Especially in wasm, many builtins don't actually need a context parameter. We currently pass Smi::kZero instead. This CL allows to generate a CallDescriptor for calling stubs without passing a context, resulting in reduced compile time and code size, and increased performance when executing these builtins. We were calling the ThrowWasm* functions without passing a context anyway (directly from code-generator-<arch>.h). With this change, we will also call the StackCheck builtin without passing a (null) context. This saves two bytes of code in each function plus each loop, and also slightly reduces compile time (very noisy, but statistically significant). Drive-by: Use NoContextConstant instead of SmiConstant(Smi::kZero).

Also unify the handling of JSCallWithArrayLike and JSCallWithSpread in the JSCallReducer to reduce the copy&paste overhead.

Changes the handling of TestResultScopes to allow them to be reused by logical tests by rewiring instead of using a new TestResultScope. Also does the following: - moves some fields about in TestResultScope to reduce it's size - moves RegisterListFreeEvent to the end of ReleaseRegisters to enable it to be tail-called. This increases the allowed depth of logical expressions which the compiler can handle without overflowing the stack by about 2x on x64.

We can remove a lot of native code and rely on CallOrConstructVarargs to do the stack manipulation for us. This will also take advantage of the fast-path for double arrays in CallOrConstructDoubleVarargs. We can also remove Runtime_SpreadIterableFixed because it isn't used anymore. We just call directly into spread_iterable from CSA.

Previously, Date.toString() and friends were completely implementation-defined. However, they actually seemed to match each other's behavior with the exception of how years less than 1000 are formatted. The rough consensus among browsers seemed to be %04d, so this was standardized at TC39 [1]. V8 previously used %4d (it was the only one to do so); this patch adopts the new standard.

For each Managed<T> (which is a Foreign), we create a weak global handle with a finalizer which deletes the referenced C++ object once the Foreign is dead. Before calling this finalizer, the garbage collector needs to mark the referenced object black (i.e. live), because the finalizer might resurrect it. Since this is never done for managed objects, we can use the more lightweight phantom handle semantics, which allows the referenced object to be garbage collected right away. However, we can't access the global handle via the WeakCallbackInfo, because the global handle will already be garbage collected. So we need to store it explicitly. This is solved by storing the global handle together with the finalizer. In order to implement this, ownership of the ManagedObjectFinalizer is moved from the isolate to the managed object.

It is possible that the foreground task is unable to clear the scheduled unfinished work, eventually leading to an OOM. We use either code_range on 64 bit, or the capacity of the code space, as a heuristic for how much memory to use for compilation. The change avoids blocking the background threads while we're over the memory threshold. This is to avoid starving the GC.

The initial implementation did not work in certain cases. For example, in the following case 'f' didn't have a shared name while it should have had an empty shared name: var f = (function() { return function() { return 42; } }(); The new implementation ensures that all anonymous functions have empty shared name and if any of them happen to be an object literal property value or an accessor function or a concise method then such a function is marked as having no shared name.
