Avi Kivity 1959f9937c test: lib: add helper to evaluate an expression with bind variables but no table ...

Sometimes we want to defeat the expression optimizer's ability to
fold constant expressions. A bind variable is a convenient way to
do this, without the complexity of faking a schema and row inputs.
Add a helper to evaluate an expression with bind variable parameters,
doing all the paperwork for us.

A companion make_bind_variable() is added to likewise simplify
creating bind variables for tests.
