PPC/s390: [crankshaft] Support all oddballs for truncating TaggedToI changes.

Port 7d383be9da728997e0c0a68500a6ac2f248240c1

Original commit message:

    For inputs to truncating binary operations like <<, | or >>>, support
    all Oddballs not just undefined, true and false. This unifies treatment
    of these truncations in Crankshaft and TurboFan, and is very easy
    nowadays, since the memory layout of Oddball and HeapNumber is
    compatible.
