sergefp@mysql.com 41404ec52e BUG#27927:Partition pruning not optimal with TO_DAYS and YEAR functions ...

- Introduced val_int_endpoint() function which converts between func 
  argument intervals and func value intervals for monotonic functions.
- Made partition interval analyzer use part_expr->val_int_endpoint()
  to check if the edge values should be included.
