Move MERGE_RR from .git/rr-cache/ into .git/
If you want to reuse the rerere cache in another repository, and set a symbolic link to it, you do not want to have the two repositories interfer with each other by accessing the _same_ MERGE_RR. For example, if you use contrib/git-new-workdir to set up a second working directory, and you have a conflict in one working directory, but commit in the other working directory first, the wrong "resolution" will be recorded. The easy solution is to move MERGE_RR out of the rr-cache/ directory, which also corresponds with the notion that rr-cache/ contains cached resolutions, not some intermediate temporary states.
