[cfe-commits] [PATCH] share code between StringRef and ArrayRef

[Jay Foad]

This patch removes a bit of code from StringRef by making it derive
from ArrayRef<char>.

Comments? OK to commit? The savings aren't huge, so I'm not
particularly wedded to the patch.

Incidentally, I didn't touch StringRef::front(), back() or
operator[](), because they return char, whereas the ArrayRef<char>
implementations would return const char &. My C++ isn't good enough to
work out whether that's an important difference or not.
