Review comment:
We can add something like `reusablePrepareInputStatements` in CodeGenerator
and place it before `reuseInputUnboxingCode` when generating the function.
Then we can make use of `reusablePrepareInputStatements` to construct the
`reusePatternLists`. But I'm fine with the current implementation as
`reusablePrepareInputStatements` is currently only useful for CEP.
