[PATCH] D47659: Give same-named members unique timestamps on Darwin in llvm-ar.

[James Y Knight via Phabricator via llvm-commits]

Herald added a reviewer: JDevlieghere.

This change ensures that the (membername,timestamp) tuple uniquely
identifies an entry in an archive for format=darwin, in deterministic
mode (which is the default).

That, then, enables lldb and dsymutil to locate the appropriate object
within the archive.
