phoenix的FlowGraph源代码之（1）：InstructionKind类型介绍

最近终于把Phoenix的FlowGraph的源代码研究透了，现在发一些笔记上来，有机会再发上来一起讨论源代码。

Member name	Description
SsaPhiInstruction	Instruction kind is SsaPhiInstruction    11
DataInstruction	Instruction kind is DataInstruction      10
LabelInstruction	Instruction kind is LabelInstruction     9
PragmaInstruction	Instruction kind is PragmaInstruction    8

后面的数字是这个枚举类型的bytes值，一想到这里就要超级鄙视一下写phoenix框架的那些家伙，变量的命名一点都不规范，充满了num1、num2这样的变量名！！
