Relax portable number check in byte compiler (bug#42147)
With bignums, the set of representable integers is no longer
platform-dependent, and since we use nothing but IEEE754 64-bit
floats, all numbers are now portable. Take advantage of this fact
to simplify constant-folding in the byte compiler, allowing it to
be applied more widely.
