For types including NaN, it is incorrect to introduce range "all" while processing a set of ranges,
even if the component ranges cover the entire value set.
This is because partial ranges don't include NaN, while range "all" does.
Example: ranges (unbounded , 1.0) and (1.0, unbounded) should not be coalesced to (unbounded, unbounded) with excluded point 1.0.
That result would be further translated to expression "xxx <> 1.0", which is satisfied by NaN.
To avoid error, in such case the ranges are not optimised.
