Performance optimization for AttributeSet#deep_dup
Skip the call to #dup, since it does a shallow copy of attributes,
which is wasted effort, since #deep_dup then replaces that
shallow copy with a #deep_dup of the given attributes.
This change addresses slowness in ActiveRecord initialization
introduced starting in Rails 5.0.
