Disambiguate between C++11 lambda expressions and C99 array
designators in the parser. In the worst case, this disambiguation
requires tentative parsing just past the closing ']', but for most
cases we'll be able to tell by looking ahead just one token (without
going into the heavyweight tentative parsing machinery).
