- Fix 18054 - Use toBool instead of toInteger when const-folding cast(bool)

  `RealExp` / `ComplexExp` may hold values that don't have a matching
  integer value (unlike `IntegerExp`). Switching to `toBool` ensures
  proper boolean conversion according to the current type.

  Teh test output shown below (before this change) was caused by the
  invalid const-folding for floating point literals.

  ```
  float: 1 == 0
  double: 1 == 0
  real: 1 == 0
  ifloat: 1 == 0
  idouble: 1 == 0
  ireal: 1 == 0
  cfloat: 1 == 0
  cdouble: 1 == 0
  creal: 1 == 0
  ```
