This method uses in messages.js in GetSourceLine and GetPositionInLine. This methods uses in v8::Message API methods and there is no documentation about it.
Method looks obsolete.
One of the strange side effect is shown by attached issue.

This allows using %OptimizeFunctionOnNextCall and friends even when
Crankshaft is disabled. Note that this should only affect code paths
that are not relevant to performance. By now we have a single bailout
point in place within OptimizedCompileJob::CreateGraph that ensures
Crankshaft is only used when enabled and supported.

Original commit message:
A hydrogen code stub is not the best approach because it builds a frame
and doesn't have the technology to discard roots at tail call exits.
Platform-specific stubs provide much better performance at this point.

  [es6] Throw TypeError for computed static prototype property name

  The prototype of a class constructor function is read only. When we set
  computed property names we were ignoring this and we were overriding the
  property.

  Since the prototype is the only possible own read only property on the
  constructor function object we special case this so we do not have to
  check this for every property in the class literal.

We were using ToObject in a lot of places where the common case is that
we already have an object. By changing to TO_OBJECT_INLINE we don't
have to go through 5 different if statements before falling through.

We were also calling ToObject too many times in DefineObjectProperty
where we already know that obj is an object.

The final spec for Object.getPrototypeOf calls ToObject on the
parameter, which means that it should only throw for null and
undefined. For other non object values the prototype of the wrapper
should be used.

    [turbofan] Implement throwing exceptions into TurboFan code.

    This extends the stack unwinding logic to respect optimized frames
    and perform a lookup in the handler table to find handlers. It also
    contains fixes to the API call stubs to allow a stack walk while
    promoting scheduled exceptions.
