[PATCH] D51652: lld-link: Write an empty "repro" debug directory entry if /Brepro is passed

[Peter Collingbourne via Phabricator via llvm-commits]

pcc added a comment.

I wasn't imagining that we'd write 32 bits of hash to the repro directory but rather the 64-bit xxhash that we currently truncate to 32 bits to get it to fit into the timestamp field. Without that, isn't there a high probability of collisions after 65536 files (which could be small depending on the project)?
