  Log Message:
  -----------
  [FreeBSD] Support -stdlib=libstdc++

The experimental-library-flag.cpp test was failing on FreeBSD builders,
which turned to be caused by missing support for -stdlib=libcstdc++ (and
just using a hardcoded libc++ in all cases).
Simplify FreeBSD::AddCXXStdlibLibArgs() by deferring to the parent class
and dealing with the FreeSBD < 14 profiling support as a special case.

While touching the test file also drop the unnecessary `-o %t.o`. This is
not needed since the RUN lines use -### and don't produce any output.
