Original commit message:
- Add a TurboFanIC class, derived from TurboFanCodeStub, that
automatically distinguishes between versions of the IC called from
optimized and unoptimized code.
- Add appropriate InterfaceDescriptors for both the versions of the
stub called from unoptimized and optimized code
- Change the MathFloor TF stub generator to output either the
for-optimized or for-unoptimized version based on the minor_key
parameter.
