    gmacros: Only set G_ANALYZER_ANALYZING to 1 when clang static analyzer is in use
    
    We set G_ANALYZER_ANALYZING to 1 when clang supporting static analyzing before,
    but this will cause compilation error when -Werror=return-type is used and the
    static analyzer is not in use because g_error static function only has
    __attribute__((analyzer_noreturn)), which is useless for normal compilation.
