   ## Which issue does this PR close?
   
   - Closes #3482 .
   
   ## What changes are included in this PR?
   
   A column promoted int->long (or float->double) keeps its originally-written 
values in manifests produced before the promotion. Partition pruning and stats 
based pruning can silently drop them, and cause data loss. 
   
   This PR fixes both problems. I can split the partition pruning and 
stats-based pruning into separate PRs if needed (currently two commits in this 
PR)
   
   ## Are these changes tested?
   
   Added tests
