0f2489d8fc macho: resolve special section/segment boundary symbols
Boundary symbols have a special name prefix:

* section$start$segname$sectname
* section$stop$segname$sectname
* segment$start$segname
* segment$stop$segname

and will resolve to either start or end of the respective
section/segment if found.

If not found, we return an error stating we couldn't find the
requested section/segment rather than silently failing and resolving
the address to 0 which seems to be the case with Apple's ld64.

2ac0ba03a6 wasm-linker: ensure symbol fields are set for decls
Previously the symbol tag field would remain `undefined` until it
was set during `flush`. However, the symbol's tag would be observed
earlier than where it was being set. We now set it to the explicit
tag `undefined` so this can be caught during debug. The symbol tag of
a decl will now also be set right after `updateDecl` and `updateFunc`.

Likewise, we now also set the `name` field during atom creation for
decls, as well as set the other fields to the max(u32) to ensure we
get a compiler crash during debug to ensure any misses will be caught.
