    Original change's description:
    > [compiler, heap] Create LocalHeap outside of ExecuteJob
    >
    > Create LocalHeap directly in the Task or in GetOptimizedCodeNow and
    > pass its reference as argument to ExecuteJob. This allows us to create
    > LocalHeap differently for the main and background thread, e.g. by
    > passing an additional argument to the constructor in the future.
    > It will be required in the future anyways when the main thread will
    > have its own LocalHeap/LocalIsolate.
    >
    > Extending the scope of LocalHeap, also made
    > HandleBase::IsDereferenceAllowed more precise and uncovered two
    > potential issues: heap accesses in
    > OptimizingCompileDispatcher::CompileNext and PipelineImpl::AssembleCode
    > with --code-comments.
    >
    > LocalHeap can now be created in the parked state. Also fixed a data
    > race with LocalHeap's destructor publishing write barrier entries
    > without holding the lock.
