Fix corruption when out of shape during ivar remove
Reproduction script: ``` o = Object.new 10.times { |i| o.instance_variable_set(:"@a#{i}", i) } i = 0 a = Object.new while RubyVM::Shape.shapes_available > 2 a.instance_variable_set(:"@i#{i}", 1) i += 1 end o.remove_instance_variable(:@a0) puts o.instance_variable_get(:@a1) ``` Before this , it would incorrectly output `2` and now it correctly outputs `1`.
