Changed paths:
  M vm.cpp
  M vm_eval.c

Log Message:
-----------
rewrite 351ebd7 and 954a8c7 because they cause crash when refer to class variable within instance_{eval, exec}'s block.

Test Script:
{{{
require 'test/unit/assertions.rb'
include Test::Unit::Assertions

@@a = 4
assert_equal(4, 1.instance_eval { @@a } )
assert_equal(4, 1.instance_exec { @@a } )

assert_raise(TypeError){ 1.instance_eval { def foo; end } }
assert_raise(TypeError){ 1.instance_eval { alias :foo :to_s} }

assert_raise(TypeError){ 1.instance_exec { def foo; end } }
assert_raise(TypeError){ 1.instance_exec { alias :foo :to_s} }

puts :ok
}}}
