Member function should contain reference to calling object

[zhuanhao-wu]

Given the following code where bhdr is of type block_header (in z7test):

// calling site
bhdr.set_exp(blockexpt);

// definition
template<typename FP> struct block_header
{
	typedef typename FP::expo_t expo_t;
	bool zb;					//full flag.
	expo_t exp;	//word
	// ...
	void set_exp(expo_t _exp) { exp = _exp;  }//"fluent" API to set exponent.

};

The generated hFunction for set_exp should contain an argument for bhdr where currently it does not. Note that the member function call itself is correctly generated

// calling site
hMethodCall zhw__block_headerfp_t11_52__set_exp_func_3 [
  hVarref bhdr_ms_proc_local_9 NOLIST
  hVarref blockexpt_ms_proc_local_12 NOLIST
]

// definition
hFunction zhw__block_headerfp_t11_52__set_exp_func_3 [
  hFunctionRetType  NONAME [
    hTypeinfo  NONAME [
      hType void NOLIST
    ]
  ]
  hFunctionParams  NONAME [
    // we need another parameter to identify the caller
    hFunctionParamI _exp [
      hTypeinfo  NONAME [
        hType sc_uint [
          hLiteral 11 NOLIST
        ]
      ]
    ]
  ]
  hCStmt  NONAME [
    hBinop = [
      hVarref _exp_actual_scclang_global_9 NOLIST
      hVarref _exp NOLIST
    ]
    hBinop = [
      hVarref exp NOLIST
      hVarref _exp_actual_scclang_global_9 NOLIST
    ]
  ]
]

Currently, we do not support the member function feature, C++ code will be modified.
