Brad King 571dc74891 Recognize Clang C and C++ compilers (see #10693)
Map to the platform and compiler information for GNU because the
compilers are command-line compatible for common operations.  Later we
can add Clang-specific features as necessary.  We honor the preferred
capitalization is "Clang", not the common mis-spelling "CLang".
