Use ANY_DIFF filter in ResolveMerger only for bare repositories
As Chris pointed out change I822721c76c64e614f87a080ced2457941f53adcd
slowed down merge since ANY_DIFF filter is much less efficient than the
manual detection of diffs done in ResolveMerger.processEntry() since it
avoids unnecessary filesystem calls using the git index. Hence only set
the ANY_DIFF filter on bare repositories which don't have a working tree
to scan.
To test performance I used the setup described in Chris' comment on
change I822721c76c64e614f87a080ced2457941f53adcd and modified
ResolveMerger.mergeTrees() to not add the working tree in order to
simulate merging in a bare repository.
At least on Mac I couldn't detect a speedup, with and without the
ANY_DIFF filter merge test takes an average 0.67sec.
