  -----------
  [ConstantFPRange][UnitTest] Ignore NaN payloads when enumerating values in a range (#111083)

NaN payloads can be ignored because they are unrelated with
ConstantFPRange (except the conversion from ConstantFPRange to
KnownBits). This patch just enumerates `+/-[S/Q]NaN` to avoid
enumerating 32 NaN values in all ranges which contain NaN values.

This patch reduces the execution time for unittests from 30.37s to
10.59s with an optimized build.
