IMPALA-4864 Speed up single slot predicates with dictionaries

When dictionaries are present we can pre-evaluate conjuncts
against the dictionary values and simply look up the result.

Status of this diff: Compiles and starts.  Bitmap tests for new
functionality pass.  FE and BE tests passing.

Going to rebase to try to get past a bug that is firing
consistently on my branch as a few fixes have gone in.
