Haxe compiler looks like it is producing incorrect code for map or set key that is binary type

Static code analysis in the gcc 7.2 build under Ubuntu Artful pointed out a missing break that may be cause for alarm:

https://github.com/apache/thrift/blob/master/compiler/cpp/src/thrift/generate/t_haxe_generator.cc#2554

https://github.com/apache/thrift/blob/master/compiler/cpp/src/thrift/generate/t_haxe_generator.cc#2579

It looks like if the type is a set or map, and the key is a binary, it will fall through to an integer for handling. This seems incorrect.
