Disambiguate nested objc-message-expressions and c++11 attributes
A couple of obj-c++ tests were failing[1] because the tokens '[[' can
either be the beginning of a c++11 attribute (that is itself at the
beginning of a statement), or the beginning of a nested
objc-message-expression. This patch resolves the ambiguity by
tentatively parsing the c++11 attribute and if it fails, then consider
the objc-message-expression.
I missed this initially because it didn't occur to me that
--enable-languages=all,ada does not include obj-c++. Shame on me. I
have now updated my compile farm scripts to use
--enable-language=all,ada,obj-c++,go and I

using c++11 attributes in non c++11 mode.
