```
wasm-linker: handle debug info during gc

When we encounter a debug info symbol, we initially have to parse it
into an atom to find its relocations. We then go through its relocations
to find out if any of the target symbols are marked alive. When it
finds an alive symbol, we also mark the debug symbol as alive to ensure
this piece of debug info is emit to the binary. When it does not encounter
any alive symbols, the debug symbol remains dead and will be garbage-
collected during `allocateAtoms`.

```
