The TraceTrait<T> checks whether T is a mixin to decide whether we can use the fast (arithmetic) or slow (bitmap) method to look up the HoH. Before this CL, the mixin application would also be considered as a mixin because the marker is present, resulting in all cases going through the object start bitmap. The initial intention was to use the arithmetic for the mixin applications as those inherit from GCed.

The compiler is only interested in the contents if it contains a FeedbackVector. If one is discovered, it is serialized, and we ensure we'll either return it or nothing if the contents of the cell changed on the main thread. FeedbackCells can be reset if the bytecode for the associated function is flushed. We have guarantees only for functions we choose to inline that this doesn't happen (by holding a strong handle to the SharedFunctionInfo).

Omer Katz authored
This CL introduces cppgc::HistogramRecorder api which is similar to the v8::metrics::Recorder api and is used by cppgc to report histogram samples to embedders. Embedders should implement the api if they want to collect histograms and provide an instance of it on heap creation. CppHeap uses an adaptor class that implements the HistogramRecorder api and is used to forward the relevant info to the relevant v8::metrics::Recorder. The api used 3 data structures: 2 for incremental steps that need to be reported as they come (marking and sweeping) and 1 for the end of a GC cycle that aggregates statistics over the entire cycle. The data structure only provide the "raw" samples (e.g. atomic mark time, incremental mark time, etc...). The embedder is expected to compute aggregate histogram on its own (e.g. overall marking time).
