In this PR we extract two new token lt (<), gt (>) from tt.relational. The base parser does not care how they are modeled as long as the binop is correctly configured. However these tokens are heavily used in the flow/jsx/typescript plugin. Introducing new tokens will simplify how plugins match these tokens: so we can remove isRelational and expectRelational method.

This PR also splits readToken_lt_gt into readToken_lt and readToken_gt.

We don't need to break for other tt.relational tokens, they will not be handled by the big switch at all and eventually thrown as unexpected token.
