[PATCH v3 1/9] diffcore-rename: rename num_create to num_destinations

["Elijah Newren via GitGitGadget" <gitgitgadget@gmail.com>]

From: Elijah Newren <newren@gmail.com>

Our main data structures are rename_src and rename_dst.  For counters of
these data structures, num_sources and num_destinations seem natural;
definitely more so than using num_create for the latter.
