Locally tested, octane results are the same or better when using branchful decompression in generated code. The biggest one is DeltaBlue in x64 which improves about 25%. x64's EarleyBoyer is another important one with ~10% improvement.

This change partially decouples the heap's allocation space numbering from the snapshot space encoding. This allows encoding read-only heap allocations when RO_SPACE is removed. A few pieces of src/snapshot also get cleaner as they no longer need to check for extraneous AllocationSpace values.

This CL completely rearchitects the ownership of array buffer backing stores, consolidating ownership into a {BackingStore} C++ object that is tracked throughout V8 using unique_ptr and shared_ptr where appropriate. Overall, lifetime management is simpler and more explicit. The numerous ways that array buffers were initialized have been streamlined to one Attach() method on JSArrayBuffer. The array buffer tracker in the GC implementation now manages std::shared_ptr<BackingStore> pointers, and the construction and destruction of the BackingStore object itself handles the underlying page or embedder-allocated memory. The embedder API remains unchanged for now. We use the v8::ArrayBuffer::Contents struct to hide an additional shared_ptr to keep the backing store alive properly, even in the case of aliases from live heap objects. Thus the embedder has a lower chance of making a mistake. Long-term, we should move the embedder to a model where they manage backing stores using shared_ptr to an opaque backing store object.

The client API provides a much simpler interface so that we don't have to deal with producers, consumers etc. directly. This CL removes all the code that dealt with the more complex API used previously. The architecture used here requires that the embedder call into Tracing::Initialize() to set up the tracing backend. The tracing controller then connects to this backend when calling DataSource::Register() and Tracing::NewTrace(). This will ultimately avoid the need for a virtual call (or two) for every trace event that need to be dispatched over the API - chrome can provide a backend and V8 will connect to it opaquely with the same code when tracing is enabled.

This removes two unneeded casts and an unused parameter. Note that according to the specification, {Allocator}s need to provide an {allocate} method receiving the size {n}, and *optionally* they can support {allocate} with a second pointer parameter which they can use in an unspecified manner. Since we do not use the second argument, we should just not provide that method. Drive-by: Remove else-after-return.

This CL aims to address the regressions that we saw in Octane 2.1, particularly in the DeltaBlue test. This CL brings a 5% improvement in said test by doing CompressedSigned -> Word32 conversion (instead of CompressedSigned -> TaggedSigned -> Word32). There seems to be room for optimizations doing more specialized conversions regarding representation changes.

Cpplint usually checks for non-const reference arguments. They are forbidden in the style guide, and v8 does not explicitly make an exception here. This CL re-enables that warning, and fixes all current violations by adding an explicit "NOLINT(runtime/references)" comment. In follow-up CLs, we should aim to remove as many of them as possible.

This CL mitigates the worst performance regressions for stack trace symbolization. The first fix is to hold the StackFrameBase instance in a local variable. The instance is produced by an iterator but newly created everytime FrameArrayIterator::Frame is called. The second fix is to skip symbolization of "MethodName" and "TypeName" for non-method calls.

This CL teaches the deoptimizer about JavaScriptBuiltinContinuation frames that are not preceded by argument adapter frames. This pattern is used when calling C++ API functions from TurboFan. This CL fixes a crash when the deoptimizer encounters the pattern described above. The crash was caused when the deoptimizer tried to read the arguments of the continuation frame. As no adapter frame was present, the argument count was read from the SharedFunctionInfo which had the kDontAdaptArgumentsSentinel value. This translated to an argument count of ~65000 later down the line, which caused a FATAL error when the deoptimizer tried to re-construct ~65000 non-existent values.
