JDK-8369186 introduced wrappers for <limits> and <type_traits> for use by HotSpot code (src/hotspot/share/{limits,type_traits}.hpp). All uses in src/hotspot were updated to use the new wrappers. However, corresponding gtest updates were initially forgotten, and then left out to avoid adding a bunch more files to that PR. Not aht JDK-8369186 has been integrated, the gtest includes should be updated.
