  1. Use streaming read I/O in SP-GiST vacuuming 

    Like 69273b8 did for GiST vacuuming, make SP-GiST vacuum use the
read stream API for vacuuming physically contiguous index pages.

Concurrent insertions may cause SP-GiST index tuples to be redirected.
While vacuuming, these are added to a pending list which is later
processed to ensure no dead tuples are left behind. Pages containing
such tuples are still read by directly calling ReadBuffer() and do not
use the read stream API.
