Add performance tests for 'for-each-ref'. The tests exercise different
combinations of filters/formats/options, as well as the overall performance
of 'git for-each-ref | git cat-file --batch-check' to demonstrate the
performance difference vs. 'git for-each-ref' with "%(*fieldname)" format
specifiers.
All tests are run against a repository with 40k loose refs - 10k commits,
each having a unique:
- branch
- custom ref (refs/custom/special_*)
- annotated tag pointing at the commit
- annotated tag pointing at the other annotated tag (i.e., a nested tag)
After those tests are finished, the refs are packed with 'pack-refs --all'
and the same tests are rerun.
