New Revision: 127701

URL: http://llvm.org/viewvc/llvm-project?rev=127701&view=rev
Log:
Create __has_feature(cxx_noexcept) and mark it as working.
Find out that our C++0x status has only one field for noexcept expression and specification together, and that it was accidentally already marked as fully implemented.
This completes noexcept specification work.
