This reverts commit cd4e5ee866.
Reason for revert: This broke the 32bit Linux SDK build.
Original change's description:
> Keep the line starts delta encoded in the VM heap as well.
>
> The line starts in the kernel binary are delta encoded. By decoding and
> storing them as int32 values, we are unneccesarily bloating the VM heap.
> This change keeps the line starts delta encoded in the VM heap as well.
> This brings down the core snapshot size by 275KB (but will of course
> affect the debug performance.)
