bug#15212: 24.3.50; c++-mode doesn't support raw string literals

[Ivan Andrus]

C++11 allows fancy new raw string literals [1], but these strings aren't
supported in c++-mode (e.g. fontification and movement by sexp's).

In my experience such raw strings are fairly rare, and they are no doubt
difficult to support.  But I thought I would report this since I
didn't see a bug for it in debbugs.
