• 1056: Allow REGEXP args to be converted
  fix for #1055
• 1054: Fix prep AS OF
  Prepared AS OFs errored when the asof target was not a bindvar. All of our previous tests treated ASOF also as a bindvar.

• 1052: enginetest: Parameterize query plan tests
• 1051: Better join commutativity count
  We excluded joins on the basis of join factors in the logical join tree,
  rather than distinct join subtrees subject to commutativity. The
  difference is that we have to permute n! to optimize the search space
  of all valid commutative trees, versus a k^n (k = table rows) execution
  runtime. 12! blocks analysis, k^12 is steep but can be OK depending on
  cardinality and indexes. We impose no limits on k^n joins.
