George Wort 30f0847c6d [turbofan][arm64] Replace TruncateInt64ToInt32(BitcastTaggedToWordForTagAndSmiBits(Load(x))) with Load(x) 
This allows arm64 to produce an extending load from ChangeInt32ToInt64(Load(x)) more frequently.
Reduces embedded code size by 0.66% for arm64.

This change gives 0.3% for Speedometer on an A55 machine.
