The exact method name is not interesting when looking at crash statistics, and can easily be retrieved from stack traces. Instead, print a consice string saying what we were trying to do when we ran OOM. This is more consistent with other OOM location strings.

It is not safe to allocate ExternalPointerTable entries while the table is being swept. This property is currently ensured by the GC. To better catch any potential future violation of this requirement, this CL now changes the Sweep() method to first set the freelist head to a special marker value, which is checked in Allocate() in debug builds and will cause a recognizable crash in release builds.

TSAN may cause the sandbox to fail to obtain enough virtual address space during initialization, thereby causing it to fall back to a smaller backing reservation. This may then in turn cause future WebAssembly.Memory allocations to fail.

If a tracing session starts after a script load has happened, then it is not emitted, so the source information is not visible in ETW. This is because we keep track of the loads already emitted, and we try to launch traces even when recording is not happening. To prevent this problem, this CS keeps track of when recording is happening. So, when it starts, it will emit all the already generated code immediately. This will add some overhead on tracing session start if system instrumentation is enabled, but this is better than not having instrumentation for previous symbols. There is still one problem: for each active isolate, it calls for replaying the event recording in an asynchronous task. So, for any JS task that is already running when tracing start, symbols will not be available. This makes this change less useful as, for a batch task or any long JS code that is already running when tracing start, we will not get symbols yet. Only after the foreground task runner runs the task to emit the ETW events we will get the symbols resolved in the trace. An specific approach was required for d8 interactive shell. As, when showing prompt, it is not processing the task runner queue, and it is only processed when the next script is launched, it first checks if it needs to generate ETW symbols information before running the script.

The fast path of Array#toSpliced currently does not correctly initialize the elements range in the copy's FixedArray elements that will hold the inserted items. A GC can occur between the initial allocation of the elements before the inserted items are copied into it, which will fail heap verification. This CL also refactors CSA's FillFixedArrayWithSmiZero method to support only zeroing a portion of a FixedArray instead of the entire thing.
