[crankshaft] Support all oddballs for truncating TaggedToI changes.

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.

Hey Yang,

Another Crankshaft unification change for type feedback in binary operations;
essentially porting behavior from TurboFan.
Please take a look.

Thanks,
Benedikt

Interpreter folks: FYI
