      [inspector] avoid cloning of async call chains · 1bca73bc
      kozyatinskiy authored 
      - separated V8StackTraceImpl and AsyncStackTrace,
- V8Debugger owns all AsyncStackTrace and cleanup half of them when limit is reached (first created - first cleaned),
- V8StackTraceImpl, AsyncStackTrace and async-task-related tables in V8Debugger have weak reference to other async stack traces.
- async tasks are cleared with related async stacks.

      [wasm] instantiate expressed in terms of compile · 71cf4890
      mtrofin authored 
      Today, the semantics of:

WebAssembly.instantiate

and

WebAssembly.compile().then(new WebAssemblyInstance)

are subtly different, to the point where attempting the proposed
change uncovered bugs.

In the future, it's possible that .instantiate actually have different
semantics - if we pre-specialized to the provided ffi, for example.
Right now that's not the case.

This CL:
- gets our implementation closer to what developers may write using
the compile -> new Instance alternative, in particular wrt promise
creation. By reusing code paths, we uncover more bugs, and keep
maintenance cost lower.

- it gives us the response-based WebAssembly.instantiate implicitly.
Otherwise, we'd need that same implementation on the blink side. The
negative is maintenance: imagine if the bugs I mentioned could only be
found when running in Blink.
