Original change's description:
> [codegen] Reduce size of safepoint table fields
>
> Code objects are often small and do not use the full integer range of PC
> offsets and deoptimization indexes. Reducing the size of these fields to
> the required size per table reduces the overall size of safepoint tables
> by roughly 25%.
