octave-lyh: libinterp/corefcn/bitfcns.cc annotate

annotate libinterp/corefcn/bitfcns.cc @ 17397:dbdff94bf977

Use std::numeric_limits for floating point bit widths * bitfcns.cc (max_mantissa_value<T>): New utility function. (Fbitshift): Use max_mantissa_value, std::numeric_limits, and sizeof. (Fbitmax): Use max_mantissa_value. Cast output properly for class single.
