Make Complex Real & Imag Op visible on int/real

[AmrDeveloper]

Currently, when performing __imag__ <int/float>, in CIR, we emit a const 0 directly, and we want to make it clear that it's ComplexImagOp, so we can use that also in the analysis.

CIR ComplexRealOp & ComplexImagOp should accept ComplexElement type (int/real) as a valid type and use those ops directly without emitting temp ComplexCreateOp

real & imag on bool are valid too and should be supported in this task too

void real_on_bool() {
  bool a;
  bool real = __real__ a;
}

void imag_on_bool() {
  bool a;
  bool imag = __imag__ a;
}
