[antlr-interest] RecognizerSharedState

[Terence Parr]

There should be only one shared state between a single instance of a parser. Each new instance will get its own shared state. There is a single shared state among all parsers imported into a root parser.

 lexer and parser share a type definition but at runtime they have different shared state.
