Merge branch 'js/partial-clone-connectivity-check'

During an initial "git clone --depth=..." partial clone, it is
pointless to spend cycles for a large portion of the connectivity
check that enumerates and skips promisor objects (which by
definition is all objects fetched from the other side).  This has
been optimized out.

* js/partial-clone-connectivity-check:
  t/perf: add perf script for partial clones
  clone: do faster object check for partial clones
