Remerge Kernel-nice.694:

Protect floorLog: 2 for case of exceptional float values (because exponent does not)
Change exponent primitive fallback code to avoid a recursion with floorLog2:
Note that I created a separate selector #exponentFromBitPattern for handling fallback, because it's
easier to test.

  	multiplied by a mantissa (between one and two). Answer with the
  	SmallInteger to whose power two is raised. Optional. See Object
