```
std.debug.Dwarf: better source location information

Two fixes here:

Sort by addresses after generating the line table. Debug information in
the wild is not sorted and the rest of the implementation requires this
data to be sorted.

Handle DW.LNE.end_sequence correctly. When I originally wrote this code,
I misunderstood what this opcode was supposed to do. Now I understand
that it marks the *end* of an address range, meaning the current address
does *not* map to the current line information.

This fixes source location information for a big chunk of ReleaseSafe
code.

```
