Merge BIT_NOT with BIT_NOR

Applies to ✅ Open Source Edition   ✅ Express Edition   ✅ Professional Edition   ✅ Enterprise Edition

The BIT_NOT function bitwise inverts its argument value. If the argument value is a BIT_NOR function, we can simply merge the two functions.

Using Settings.transformPatternsBitNotNor, the following transformations can be achieved:

-- With Settings.transformPatternsBitNotNor active, this:
  ~(bitnor(a, b)),
  ~(bitor(a, b))
FROM tab;

-- ... is transformed into the equivalent expression:
  bitor(a, b), -- ~(bitnor(a, b))
  bitnor(a, b) -- ~(bitor(a, b))
FROM tab;
