  Log Message:
  -----------
  [ELF] Make --trace-symbol track preempted shared definitions

Note, we still name a preempted SharedSymbol "shared definition",
instead of "reference" as printed by GNU ld. This difference should not matter.

```
// GNU ld
ld.bfd: t: definition of f at v1
ld.bfd: t.so: reference to f at v1
```
