Alex Lorenz 1f79297ebe Recommit r335063: [Darwin] Add a warning for missing include path for libstdc++
The recommit ensures that the tests that failed on bots don't trigger the warning.

Xcode 10 removes support for libstdc++, but the users just get a confusing
include not file warning when including an STL header (when building for iOS6
which uses libstdc++ by default for example).
This patch adds a new warning that lets the user know that the libstdc++ include
path was not found to ensure that the user is more aware of why the error occurs.
