<pre>Initially reported by Chromium at <a href="https://crbug.com/v8/8502">https://crbug.com/v8/8502</a>
The problem here is that ModuleSymbolTable uses RecordStreamer to scan the
inline assembly for the information that it needs, and RecordStreamer uses the
default implementation for COFF directives (inherited from MCStreamer), which
executes llvm_unreachable.</pre>
