cbuffer A {

  float a;
  float b;

}

will be translated to a global variable with special address space.

Something like

struct CB_Ty {

  float a;
  float b;

};

__attribute__((address_space(3)))
CB_Ty A;

And all use of a and b will be replaced with A.a and A.b.

Only support none-legacy cbuffer layout now.
CodeGen for Resource binding will be in separate patch.
