The big changes are: - Deleting Driver/(Arg|Opt)* - Rewriting includes to llvm/Option/ and re-sorting - 'using namespace llvm::opt' in clang::driver - Fixing the autoconf build by adding option everywhere As discussed in the review, this change includes using directives in header files. I'll make follow up changes to remove those in favor of name specifiers. Reviewers: espindola Differential Revision: http://llvm-reviews.chandlerc.com/D975 llvm-svn: 183989
