We should avoid doing pointer math with CodeBlock::instructions().begin(). Instead, we should use the operator[] that comes with CodeBlock::instructions() for computing an Instruction*, and use CodeBlock::bytecodeOffset() for computing the bytecode offset of a given Instruction*. These methods will do assertions which helps catch bugs sooner, plus they are more descriptive of the operation we're trying to do.
