[llvm-dev] New LLVM git repository conversion prototype

[James Y Knight via llvm-dev]

I've regenerated the repository set at
https://github.com/jyknight/llvm-git-migration again, with these fixes.

James, could you prune r70891? It cuts the history.


Done.

Done.

Done, and double-checked again against the old git conversion.

I also took the opportunity to add some more fixups for CVS issues back to
the 1.0 release. I've now also now verified that the file moving done by
these CVS fixes didn't end up accidentally losing changes, by iterating
over all the commits and ensuring that file hashes in a recursive ls-tree
have not disappeared from the commit (just changed their path).
