When inserting the temporary cache key for synchronous compilation, use the NativeModule's owned wire bytes. When we eventually install the native module, key comparison can then take the fast path by checking base pointer equality instead comparing the full bytes.

This is a reland of change Idb1061cafcba7a2a654a207402dca520f79a3bbe. The access to wire_bytes has been protected by using atomic operations. Under some circumstances, Wasm is trying to log code for which the wire bytes are not fully loaded yet. This can happen during streaming compilation when a few functions are already fully compiled but the engine is still streaming the remaining functions. If the profiler now kicks in, it will attempt to log these freshly compiled functions. As these functions will not be executed before the module is fully compiled, we can simply defer the logging in this case.

We currently hit a nullptr access when trying to update the detected feature set.

We want to enable the wasm-bigint implementation by default. However, at the moment there exist several tests which fail when wasm-bigint gets enabled. With this CL we adjust or delete these tests so that they pass once wasm-bigint gets enabled. At the same time we disable these tests for now, and re-enable them in the CL that flips the flag.

Instead, repurpose it during register allocation so that it always holds the last hint position found for this top level live range. This ensures that each use position is visited at most once even when the range is split.

Unified heap support in V8 requires having another (at least internal) heap that implements a unfied garbage collection strategy. This will not re-use the already existing cppgc::Heap because there should be no way in creating such a heap externally or scheduling stand-alone garbage collections. In order to have a common token, this CL introduces AllocationHandle which can be passed to MakeGarbageCollected to allocate C++ objects. V8 (soon) and the stand-alone heap both have methods to retrieve such a handle. This works around a problem with creating diamond class hierarchies when a base class would be exposed on the public API level. Fast paths for Blink are still possible because allocation handles can be cached the same way (e.g. global, or TLS) as a heap can be cached.

Making them private was a way to hide the functions, we can explicitly delete them, which give a better compilation error message as well.

This is a reland of f7f72b7b This was reverted because of a test timing out on slow_path variant (https://crrev.com/c/2237131 for details). Turns out the test is just really slow, and was skipped on this variant in https://crrev.com/c/2237628. Relanding without changes.
