To inject a modulemap into the libstdc++ directory, Swift needs to know the path of the libstdc++ installation. Previously it was assumed to be `/usr/include/c++/{version}`, however, this might not be the case. For example, on CentOS the stdlib is located at `/opt/rh/devtoolset-{version}/root/usr/include/c++/{version}`.
This change teaches Swift to extract the libstdc++ include paths from the Clang driver, and fixes C++ stdlib lookup on CentOS.
