Thomas Lively 0fd5e7b2d8 [WebAssembly][lld] Fix segfault on .bss sections in mapfile 
When memory is declared in the Wasm module, we rely on the implicit zero
initialization behavior and do not explicitly output .bss sections. The means
that they do not have associated `outputSec` entries, which was causing
segfaults in the mapfile support. Fix the issue by guarding against null
`outputSec` and falling back to using a zero offset.
