Module.instance_eval not working

[sasq64]

The following code fails with
uninitialized constant #<Class:0x68fa70>::A (NameError)

     m = Module.new
     m.instance_eval("
     class A end
     class B
         def initialize()
             p A
         end
     end
     B.new
")

Also, after you get this error, plain eval() also breaks for the same code...

Shorter repro:

 Module.new.class_eval("
 class A end
 class B
     p A
 end
")

It's caused by #5497. Shall I revert it @dearblue?

[matz]

#5497 reverted. @dearblue please retry.

@sasq64 Thank you for reporting the issue.
@matz Thank you for revert #5497. If done well, I'll PR again.
