write_tree_from_memory() appeared to be a merge-recursive special that
basically duplicated write_index_as_tree(). The two have a different
signature, but the bigger difference was just that write_index_as_tree()
would always unconditionally read the index off of disk instead of
working on the current in-memory index. So:
* split out common code into write_index_as_tree_internal()
* rename write_tree_from_memory() to write_inmemory_index_as_tree(),
make it call write_index_as_tree_internal(), and move it to
cache-tree.c
