Bug #10114: syntax error raised from instance_eval has unexpected encoding

* Target version: 
* ruby -v: 2.0.0, 2.1.1, 2.1.2 are affected. 1.9.3 is not
* Backport: 2.0.0: REQUIRED, 2.1: REQUIRED
----------------------------------------
~~~ruby
#!/usr/bin/env ruby
# -*- coding: utf-8 -*-

code = 'def n "Ēš"; end'
puts "code.encoding: #{code.encoding} #{code.valid_encoding?}"

begin
  instance_eval(code)
rescue SyntaxError => error
  puts "error.message.encoding: #{error.message.encoding} #{error.message.valid_encoding?}"
end
~~~

Outputs the following:

~~~
code.encoding: UTF-8 true
error.message.encoding: ASCII-8BIT true
~~~

but I expect error.message.encoding to be UTF-8.
