Please add a comment somewhere (not necessarily here) with a TODO pointing to
the V8 source file where they set up these types for Android.

-    // Extract thread state.
-    ucontext_t* context = reinterpret_cast<ucontext_t*>(context_);
-    mcontext_t mcontext = context->uc_mcontext;
-    InterruptedThreadState its;
-    its.tid = state->id;
-    its.pc = SignalHandler::GetProgramCounter(mcontext);
-    its.fp = SignalHandler::GetFramePointer(mcontext);
-    its.sp = SignalHandler::GetStackPointer(mcontext);
-    state->callback(its, state->data);
   }
