New Revision: 174530

URL: http://llvm.org/viewvc/llvm-project?rev=174530&view=rev
Log:
Accept and ignore the -fextended-identifiers option.

This was GCC's option to turn on UCN support, which we always have on now
in C99 and C++ modes.

Additionally, mark the -fno-extended-identifiers option as unsupported,
since we don't support disabling UCNs in C99 and C++ modes.
