Remove unneeded old_rel_pages VACUUM state field.

The field hasn't been used since commit 3d351d91, which redefined
pg_class.reltuples to be -1 before the first VACUUM or ANALYZE.

Also rename a local variable of the same name ("old_rel_pages"). This is
used by relation truncation to represent the original relation size at
the start of the ongoing VACUUM operation.  Rename it to orig_rel_pages,
since that's a lot clearer.  (This name matches similar nearby code.)
