Merge commit 585a3cc31 from llvm git (by me):

Fix -Wdeprecated-copy-dtor and -Wdeprecated-dynamic-exception-spec
  warnings.

  Summary:
  The former are like:

  libcxx/include/typeinfo:322:11: warning: definition of implicit copy
  constructor for 'bad_cast' is deprecated because it has a
  user-declared destructor [-Wdeprecated-copy-dtor]
    virtual ~bad_cast() _NOEXCEPT;
	    ^
  libcxx/include/typeinfo:344:11: note: in implicit copy constructor
  for 'std::bad_cast' first required here
      throw bad_cast();
	    ^

  Fix these by adding an explicitly defaulted copy constructor.

  The latter are like:

  libcxx/include/codecvt:105:37: warning: dynamic exception
  specifications are deprecated [-Wdeprecated-dynamic-exception-spec]
      virtual int do_encoding() const throw();
				      ^~~~~~~

  Fix these by using the _NOEXCEPT macro instead.

  Differential Revision: https://reviews.llvm.org/D76150

This is because we use -Wsystem-headers during buildworld, and the two
warnings above are now triggered by default with clang 10, preventing
most C++ code from compiling without NO_WERROR.
