  Log Message:
  -----------
  [lld][Wasm] Wasm-ld emits invalid .debug_ranges entries for non-live symbols

When the debug info contains a relocation against a dead symbol, wasm-ld
may emit spurious range-list terminator entries (entries with Start==0
and End==0). This change fixes this by emitting the WasmRelocation
Addend as End value for a non-live symbol.
