What are the platform-specifics for crash reproducing? Shouldn't it
basically be saving some files and storing some data for reconstructing?
We've recently been working on a `--reproduce` for LLD and we haven't
needed any ifdefs for windows (some tests that rely on really long path
names need to be turned off, but the feature still works).
