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.
