  -----------
  [VPlan] Add more generic VPCostContext::getCostDivisor (NFC). (#225413)

Replace getReplicateRegionCostDivisor with more general getCostDivisor,
which takes a frequency directly.

The frequency lookup is now done at the 3 call sites, which all have the
region at hand.

Will also be used in https://github.com/llvm/llvm-project/pull/196845.
