<pre>lld-link crashes if trying to link any .obj file compiled with /Z7 and /Yu
option. It crashes in TypeStreamMerger::remapIndex function in
LastError = joinErrors(std::move(*LastError), errorCorruptRecord());
because LastError is nullopt. If you fix this segfault "The CodeView record is
corrupted." error is printed. The problem is probably because LF_PRECOMP record
is not handled at all.</pre>
