Make copy of InsnNode object.
NOTE: can't copy instruction with result argument (SSA variable can't be used in two different assigns).
Prefer use next methods:

• copyWithoutResult() to explicitly state that result not needed
• copy(RegisterArg) to provide new result arg
• copyWithNewSsaVar(MethodNode) to make new SSA variable for result arg
