Speed up CREATE INDEX CONCURRENTLY's TID sort.

Encode TIDs as 64-bit integers to speed up comparisons.  This seems to
speed things up on all platforms, but is even more beneficial when
8-byte integers are passed by value.

Peter Geoghegan.  Design suggestions and review by Tom Lane.  Review
also by Simon Riggs and by me.
