C# Class Reko.Arch.M68k.OperandRewriter

Rewrites M68k operands into sequences of RTL expressions and possibly instructions.
Some of the operands, like (A6)+ and -(A5), have side effects that need to be expressed as separate instructions. We must therefore insert RTL instructions into the stream as these operands are rewritten. Because of these side effects, it is critical that we don't call Rewrite twice on the same operand, as this will cause two side effect instructions to be generated.
