This is just a hack until yangguo lands this:

   Runtime::InitializeIntrinsicFunctionNames(isolate(), intrinsic_names);
   set_intrinsic_function_names(*intrinsic_names);

   // Allocate cache for single character one byte strings.
   set_single_character_string_cache(
       *factory->NewFixedArray(String::kMaxOneByteCharCode + 1, TENURED));
