Currently the test on line 3 is identical to the test on line 1.
Looking at the rest of the file (particularily the use of FOVERRIDE
as the check-prefix), I think it's pretty clear that this line
was supposed to use `-ftrigraphs` instead of `-trigraphs`.

-trigraphs is now an alias for -ftrigraphs. -fno-trigraphs makes it possible
to explicitly disable trigraphs, which couldn't be done before.
clang -std=c++11 -fno-trigraphs
now builds without GNU extensions, but with trigraphs disabled. Previously,
trigraphs were only disabled in GNU modes or with -std=c++1z.
Make the new -f flags the cc1 interface too. This requires changing -trigraphs
to -ftrigraphs in a few cc1 tests.
