Avoid loading an undefined value in the ranger_cache constructor.
Enable_new_values takes a boolean, returning the old value. The constructor for ranger_cache initialized the m_new_value_p field by calling this routine and ignorng the result. This potentially loads the old value uninitialized. * gimple-range-cache.cc (ranger_cache::ranger_cache): Initialize m_new_value_p directly.
