C++: Basic support for C++11 user-defined literals 1. Extends lexer so digit or string can be followed by underscore '_' and alphanumeric defining literal. 2. Extends parser so it accepts operator"" _abc(...) user-defined literal definition. 3. Adds Token::Flags.userDefinedLiteral bool flag field representing if token carries user-defined literal. 4. Adds C++11 auto tests case with: 12_km, 0.5_Pa, 'c'_X, "abd"_L, u"xyz"_M 5. All optional suffix scanning methods now return boolean if the suffix was found. 6. Adds C++ Lexer tests for user-defined literals with C++11 feature enabled. This change however does not make QtCreator understand user-defined literal semantics, e.g. properly resolve type when applying custom literal operator.

Built-in lexer: Recognize also reserved user-defined literals Otherwise, we trip over uses of operators from the standard library such as std::chrono's operator"" ms(), potentially breaking basic code navigation.
