[ruby/irb] Simplify RubyLex.compile_with_errors_suppressed
nobu-san reviewed,
https://github.com/ruby/irb/pull/106#pullrequestreview-423400033
> How about lexer = Ripper::Lexer.new(";\n#{code}", nil, 0)?
> Encoding pragma is effective only at the beginning.
> And the semicolon and newline will be skipped because the position is before
> the initial pos.
I employ the way.
