So a block range is `[offset, offset + size)`, where offset is relative to the
parent function's entry point.
You want to make AddressRange which is a proper virtual address (minus the
generally applied load offset). So you make it `[function entry point + offset,
function entry point + offset + size)` by adding the function entry point to
the base of the range.
If any of that is a correct interpretation, consider adding a comment to
explain that in the code:
```
// The block's base address is a relative offset to its parent function's entry
point. We want to produce a virtual address
// so we need to add the value of that entry point here.
```
