  -----------
  [RegAllocEvictionAdvisor] Make the local reassign option more useful (#223115)

Prior to this patch the CLI option for the local reassignment heuristic
could only force enabling the local reassignment heuristic. In other
words, there was no way to disable the heuristic if the target hook said
otherwise, which defeated the purpose of the option.

Fix this by ensuring that when the option is set it takes precedence
over the target hook. This makes experimenting with the local
reassignment heuristic much easier.

The patch is NFC unless you set the option.
