The original peephole optimizer logic in the BytecodeArrayBuilder did not respect source positions as it was written before there were bytecode source positions. This led to some minor differences to FCG and was problematic when combined with pending bytecode optimizations. This change makes the new peephole optimizer fully respect source positions.
