r315856 - Add -f[no-]double-square-bracket-attributes as new driver options to control use of [[]] attributes in all language modes. This is the initial implementation of WG14 N2165, which is a proposal to add [[]] attributes to C2x, but also allows you to enable these attributes in C++98, or disable them in C++11 or later.

I have no problems renaming it, but I'm not keen on "generalized". The
name used in the WG21 proposal papers was "general attributes" (sort
of, the term was used once in the paper, and not in the title), but I
don't think I've seen any community consensus on calling them that.
While the current name is a mouthful, it's at least descriptive as to
which of the four attribute syntaxes we're talking about.
