Add mandatory C++ compiler build dependency

This change is in preparation of converting some internal code to C++.

 - Add ax_cxx_compile_stdcxx.m4, which provides AX_CXX_COMPILE_STDCXX, a
   macro to find a C++ compiler matching certain characteristics.
 - Find which warning flags work for the C++ compiler (certain warning
   flags may be C or C++ specific).
 - Do a bit of reorganizing to group all C compiler things together, all
   C++ compiler things together.
