In the recent changes to make the planner account better for cache
effects in a nestloop inner indexscan, I had only dealt with plain index
scans and the index portion of bitmap scans. But there will be cache
benefits for the heap accesses of bitmap scans too, so fix
cost_bitmap_heap_scan() to account for that.

Ah, I finally realize why Magnus wanted to add a --bindir option to
pg_regress: there's no other way to cope with testing a relocated
installation. Seems better to call it --psqldir though, since the
only thing we need to find in that case is psql. It'd be better if
we could use find_other_exec, but that's not happening unless we are
willing to install pg_regress alongside psql, which seems unlikely
to happen.

Don't try to truncate multixact SLRU files in checkpoints done during xlog
recovery. In the first place, it doesn't work because slru's
latest_page_number isn't set up yet (this is why we've been hearing reports
of strange "apparent wraparound" log messages during crash recovery, but
only from people who'd managed to advance their next-mxact counters some
considerable distance from 0). In the second place, it seems a bit unwise
to be throwing away data during crash recovery anwyway. This latter
consideration convinces me to just disable truncation during recovery,
rather than computing latest_page_number and pushing ahead.

Adjust spawn_process() to avoid unnecessary overhead processes: we can

Ensure that we retry rather than erroring out when send() or recv() return
EINTR; the stats code was failing to do this and so were a couple of places
in the postmaster. The stats code assumed that recv() could not return EINTR
if a preceding select() showed the socket to be read-ready, but this is
demonstrably false with our Windows implementation of recv(), and it may
not be the case on all Unix variants either. I think this explains the
intermittent stats regression test failures we've been seeing, as well
as reports of stats collector instability under high load on Windows.
