The signature of {GetMaxConcurrency} was recently extended to pass the {worker_count}, i.e. the number of workers that are currently running. This number allows us to return a more precise number for the current maximum concurrency. In the case of background function compilation, we were sometimes returning a slightly too small number, resulting in too few workers to be spawned, resulting in slightly longer compilation. For wrapper compilation on the other hand, the returned number is already correct, and this CL adds a comment explaining why.

If code is deoptimized while CPU profiling, a deoptimization event record is sent to the profiler. But if the profiler could not find the associated CodeMap entry in CodeDeoptEventRecord::UpdateCodeMap it would simply return without freeing the deopt_frames array. This change frees the deopt_frames array no matter what in CodeDeoptEventRecord::UpdateCodeMap, eliminating a storage leak.

all_true requires the input to be of the respective type, but the final result is always a Int32x4 with a single node. So keep the replacement type of all_true (and any_true) nodes to be Int32x4, and use a helper method to decide what SimdType the input should be replaced with. Also split up any_true and all_true for readability.

Concurrent allocation uses Isolate::is_profiling() to determine whether logging is on. This races with the main thread when the value in is_profiling is switched on/off by the cpu profiler. Fix this by making is_profiling relaxed atomic. The profiler doesn't turn off logging for correctness reasons, so it is fine when background threads may read an old value and continue logging a bit longer. It is also okay when background threads start logging again a bit longer when profiling is stopped.

This commit adds a check in Heap::AllocateRaw when setting the large_object variable, when the AllocationType is of type kCode, to take into account the size of the CodeSpace's area size. The motivation for this change is that without this check it is possible that size_in_bytes is less than 128, and hence not considered a large object, but it might be larger than the available space in code_space->AreaSize(), which will cause the object to be created in the CodeLargeObjectSpace. This will later cause a segmentation fault when calling the following chain of functions: if (!large_object) { MemoryChunk::FromHeapObject(heap_object) ->GetCodeObjectRegistry() ->RegisterNewlyAllocatedCodeObject(heap_object.address()); } We (Red Hat) ran into this issue when running Node.js v12.16.1 in combination with yarn on aarch64 (this was the only architecture that this happed on).
