Richard Guo 0aaf0de7fe Optimize BooleanTest with non-nullable input ...

The BooleanTest construct (IS [NOT] TRUE/FALSE/UNKNOWN) treats a NULL
input as the logical value "unknown".  However, when the input is
proven to be non-nullable, this special handling becomes redundant.
In such cases, the construct can be simplified directly to a boolean
expression or a constant.
