Detailed Description

Represent parallel IR assignment, such as:
EAX = EBX
EBX = EAX

-> Exchange between EBX and EAX

AssignBlock can be seen as a dictionary where keys are the destinations
(ExprId or ExprMem), and values their corresponding sources.

Also provides common manipulation on this assignments.

__init__()

def miasm.ir.ir.AssignBlock.__init__	(		self,

			instr = None
	)

Create a new AssignBlock
@irs: (optional) sequence of ExprAssign, or dictionary dst (Expr) -> src
      (Expr)
@instr: (optional) associate an instruction with this AssignBlock
