EscapeRegExpPattern should return a string representation of a RegExp instance that in turn can be used to construct a new RegExp instance with the same internal state as the original one. Previous versions incorrectly escaped '/' also inside character classes (e.g. /[/]/ returned "[\/]"). This patch properly escapes '/' when necessary and omits unnecessary escapes.

The current integration of crash keys into v8 got the dependencies wrong: it introduced into v8 a dependency on components and base. This change will allow moving the implementation into "gin" (via Platform's abstraction), which is ok to depend on components and base, while providing the default noop implementation for the embedders that don't care to collect crash keys.

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.
