[issue25984] Expose a simple "is IEEE 754" flag in sys.float_info

[random832]

New submission from random832:

I think it would be useful for programs to be able to detect whether a system 
uses IEEE-754 double-precision values for the 'float' type. There is lots of 
detailed information about the float type in sys.float_info, but no simple "is 
IEEE" flag. On some C implementations, this is exposed as __STDC_IEC_559__.
