- New options '-mrtm'/'-mno-rtm' are added to enable/disable RTM feature - Builtin macro '__RTM__' is defined if RTM feature is enabled - RTM intrinsic header is added and introduces 3 new intrinsics, namely '_xbegin', '_xend', and '_xabort'. - 3 new builtins are added to keep compatible with gcc, namely '__builtin_ia32_xbegin', '__builtin_ia32_xend', and '__builtin_ia32_xabort'. - Test cases for pre-defined macro and new intrinsic codegen are added. llvm-svn: 167665
