There are a few places that also need to check symbol aliases before `Irb#eval_input`. But since the current command test skip them, we don't have test coverage on them.

This will save RubyLex from knowning information about commands and aliases.

(ruby/irb#683) * Add a test case for Ctrl-C handling * Test symbol aliases with integration tests There are a few places that also need to check symbol aliases before `Irb#eval_input`. But since the current command test skip them, we don't have test coverage on them. * Move each_top_level_statement and readmultiline to Irb This will save RubyLex from knowning information about commands and aliases. ruby/irb@69cb5b5615

This PR moves the remaining input processing logic from
RubyLextoIrb. It will enable a few refactors:RubyLex's@contextis only used to get local variables, we can remove it completely by passing locals as arguments. I will open a PR for this after this is merged.Irbcontrols a large part of an input's lifecycle (from reading to pre-evaluation), we can shorten the process or at least make it easier to understand.In addition to the refactor, I also added/improved a few test cases to cover what we were missing.
