Fix adding unescaped slash token when splitting gcc case range. (#1987) 

* Fix adding unescaped slash token when splitting gcc case range.

Construction like case '!'...'~' converted to a list of separate case
tokens. When slas '\' symbol appears as a part of this list it was added
"as is", but it should be escaped like '\\' to be valid c++ code.

* Add test for switch-case range with slash
