bmeurer 385734bf11 [turbofan] Let ChangeFloat64ToTagged canonicalize to Smi if possible.
When the incoming value to ChangeFloat64ToTagged is in Smi range, we
represent it as Smi instead of a HeapNumber. This addresses a range of
problems where TurboFan unnecessarily deoptimizes because an operation
learned Smi feedback in Ignition, but was then confronted with a tagged
HeapNumber in TurboFan, just because the value was also represented as
unboxed double somewhere in the meantime.
