I think the attempt to reuse this vector for both cases - with and without partitioning makes the code more complex than it needs to be. Consider the following refactoring:
* Sink the vector into the if condition below.
* Use separate vectors for hot and cold when partitioning is enabled.
* Use an arrayref as param for emitJumpTableImpl instead of iterator range.
