[VPlan] Make sure properlyDominates(A, A) returns false.

At the moment, properlyDominates(A, A) can return true via
LocalComesBefore. Add an early exit to ensure it returns false if
A == B.

Note: no test has been added because the existing test suite covers this
case already with libc++ with assertions enabled.

Fixes https://github.com/llvm/llvm-project/issues/60850.
