Support "IS TRUE/FALSE" syntax (redo)

[sarahyurick]

Which issue does this PR close?

Closes#3159

What changes are included in this PR?

Redo of #3189 with the IsNotDistinctFrom operator instead, from @alamb's suggestion. Includes SQL-level tests as well.

Since IS TRUE and IS FALSE should only work on boolean and null datatypes, we are waiting on #3222 so that we can add type validation.
