  Log Message:
  -----------
  [LV] Disable VPlan-based cost model for 19.x release.

As discussed in  https://github.com/llvm/llvm-project/pull/92555 flip
the default for the option added in
https://github.com/llvm/llvm-project/pull/99536 to true.

This restores the original behavior for the release branch to give the
VPlan-based cost model more time to mature on main.
