[ruby/irb] Always use local variables in current context to parse code (https://github.com/ruby/irb/pull/397)

* Use local_variables for colorize, code_block_open check, nesting_level and assignment_expression check

* Check if expression is an assignment BEFORE evaluating it. evaluate might define new localvars and change result of assignment_expression?

* Add local_variables dependent code test

* pend local variable dependent test on truffleruby

code_block_open is not working on truffleruby

* Always pass context to RubyLex#lex

* Rename local_variable_assign_code generator method name

* Add assignment expression truncate test

* Add Context#local_variables and make generate_local_variables_assign_code more simple

* Update lib/irb/input-method.rb

* Add a comment why assignment expression check should be done before evaluate
