Returns whether the attributes of this method can be copied from the attributes of the given
method (assuming there is no method visitor between the given ClassReader and this
MethodWriter). This method should only be called just after this MethodWriter has been created,
and before any content is visited. It returns true if the attributes corresponding to the
constructor arguments (at most a Signature, an Exception, a Deprecated and a Synthetic
attribute) are the same as the corresponding attributes in the given method.
