Description:
 def equiv(self, instr):
 """Check equivalence of instructions. This checks against the types and the arguments of the instructions Parameters instr : Instruction The instruction to check against. Returns ------- is_equiv : bool If the instructions are equivalent. Notes ----- This is a separate concept from instruction identity. Two separate instructions can be equivalent without being the same exact instance. This means that two equivalent instructions can be at different points in the bytecode or be targeted by different jumps. """
