Nico Weber 83e60f5a55 [lld/mac] Add --reproduce option ... This adds support for ld.lld's --reproduce / lld-link's /reproduce: flag to the MachO port. This flag can be added to a link command to make the link write a tar file containing all inputs to the link and a response file containing the link command. This can be used to reproduce the link on another machine, which is useful for sharing bug report inputs or performance test loads. Since the linker is usually called through the clang driver and adding linker flags can be a bit cumbersome, setting the env var `LLD_REPRODUCE=foo.tar` triggers the feature as well. The file response.txt in the archive can be used with `ld64.lld.darwinnew $(cat response.txt)` as long as the contents are smaller than the command-line limit, or with `ld64.lld.darwinnew @response.txt` once D92149 is in. The support in this patch is sufficient to create a tar file for Chromium's base_unittests that can link after unpacking on a different machine.
