cache-tree: create/update cache-tree on checkout
When git checkout checks out a branch, create or update the
cache-tree so that subsequent operations are faster.
update_main_cache_tree learned a new flag, WRITE_TREE_REPAIR. When
WRITE_TREE_REPAIR is set, portions of the cache-tree which do not
correspond to existing tree objects are invalidated (and portions which
do are marked as valid). No new tree objects are created.
