  Log Message:
  -----------
  [VPlan] Remove unneeded getNumUsers calls in replaceAllUsesWith (NFC).

As suggested post-commit for a00227197, replace unnecessary getNumUsers
calls by boolean variable to indicate if users changed. Note that this
also requires an early exit to detect the case where a value is replaced
by itself.
